ci: annotate the lockfix permissions with sentinel accepts

[bgard68]

Adds the sentinel:accept GHA002 markers to the two permission lines in dependabot-lockfix.yml, with the reason on the line the scanner flags:

permissions:
  contents: write  # sentinel:accept GHA002 - pushes the regenerated lock files to the Dependabot branch
  actions: write   # sentinel:accept GHA002 - approves the PR checks GitHub creates after the bot push

Each scope is used by exactly one step — contents: write by "Push the fix if anything changed" (git push origin HEAD:$BRANCH), actions: write by "Approve the pull-request checks on the fixed commit" (POST .../actions/runs/{id}/approve) — so there is nothing for GHA002 to act on beyond recording that.

This returns the declaration to the workflow level so the markers sit on the lines GHA002 reports, and drops the job-level block added in #142, so there is one place to read the answer instead of two.

Effective permissions are unchanged. The file has a single job, which now inherits exactly what it previously overrode with:

before  workflow: {contents: read}                    job: {contents: write, actions: write}
after   workflow: {contents: write, actions: write}   job: inherits

The one thing lost is the "a second job added here starts read-only" property from #142. That only matters if this file ever gains another job, and the markers are worth more than a hypothetical.

cleanup-runs.yml still carries its actions: write at job level with no marker — say the word and it gets the same treatment on both main and dapper.
