ci: make the path filter's exclusions take effect

[goosewobbler]

Proposed changes

Sets predicate-quantifier: some-with-excludes on the dorny/paths-filter step in test.yml, so the '!' exclusions in the code filter take effect.

Current behavior: with the default quantifier, some, a file matches a filter if any one of its patterns matches, and a '!' pattern matches every file outside its own tree. Every file is outside at least one excluded tree, so code is true for every PR, and every PR runs the full core suite. For example, webdriverio/webdriverio#15811 (README, BACKERS and website docs) and webdriverio/webdriverio#15839 (.agents and website docs) each ran 24 jobs, including build, unit, typings, interop, smoke and every core e2e.

After: an exclusion is final, which is how pnpm run test:changed already classifies files. A PR whose files all fall in excluded trees, or in no lane, runs only the lanes it touches:

PR touches only	Still runs	Stops running
website/	static analysis, docs build	build, typings, interop, unit, smoke, launch, testrunner, multi-remote, standalone
infra/docs	static analysis, docs build (with the @wdio/docs unit tests)	same
packages/wdio-session, e2e/session	build, static analysis, unit, session e2e	typings, interop, smoke, launch, testrunner, multi-remote, standalone
packages/wdio-display-server, e2e/wdio/display-server	build, static analysis, unit, display-server	same
packages/wdio-browser-runner, e2e/browser-runner	build, static analysis, typings, unit, component	interop, smoke, launch, testrunner, multi-remote, standalone
paths in no lane: root markdown, .agents/, examples/	static analysis	everything else

PRs that also touch other code, PRs that touch CI or root config, and pushes to main and v10 still run everything.

What's skipped can't be affected:

• Nothing in CI reads root markdown or .agents/. Static analysis lints examples/, and it always runs.
• @wdio/runner and @wdio/cli load @wdio/session lazily, only for --debug agent, wdio repl --session and wdio session, which the session lane tests.
• The display-server lane runs the testrunner through @wdio/local-runner. packages/wdio-local-runner isn't excluded, so changes to it still run the core suite.

How you tested

• Three throwaway PRs on this fork, each changing only the files listed. Their Detect Changes logs show:

  PR	Base	Files	code
  before	upstream-v10	a website doc, packages/wdio-session/README.md	true
  after	this branch	the same two files	false (docs and session true)
  control	this branch	packages/webdriverio/README.md	true

  The after run went to completion and ran 10 jobs, all green: build, static analysis, unit, session e2e and the docs build. It skipped typings, interop, smoke, component, display-server and every core e2e.

• Ran dorny/paths-filter's own Filter (src/filter.ts at the pinned commit) against this workflow's filters with both quantifiers, with the same results.

• actionlint passes.

• This PR changes .github/workflows/**, so its own CI runs everything.

Types of changes

• Polish (an improvement for an existing feature)
• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update (improvements to the project's docs)
• Specification changes (updates to WebDriver command specifications)
• Internal updates (everything related to internal scripts, governance documentation and CI files)

Checklist

• I have read the CONTRIBUTING doc
• I have added tests that prove my fix is effective or that my feature works
• I have added the necessary documentation (if appropriate)
• I have added proper type definitions for new commands (if appropriate)

Further comments

• main has the same issue in its xvfb, browser-runner and scripts/docs-generation exclusions, and the same line fixes it.
• This PR is independent of feat(@wdio/utils): download Chromedriver from Electron releases #10 and merges cleanly in either order. Once both land, feat(@wdio/utils): download Chromedriver from Electron releases #10's e2e/wdio/chromedriver/** exclusion takes effect too.
