feat: use GetFiles for --patch-templates to support local directories

[Venkatesh1505]

Description

The --patch-templates flag in score-compose init used uriget.GetFile which only supports single file URIs. This change replaces it with uriget.GetFiles, which additionally supports passing a local directory path to load all patch template files from it at once.

This mirrors the same change already done for the --provisioners flag in PR #465

Related issue: score-spec/score-go#177

What does this PR do?

Enables --patch-templates to accept a local directory path, loading all files within it as patch templates. Previously, only individual file paths and remote URIs were supported.

All existing behavior (single file, remote URI, stdin) remains unchanged.
