Enable mt-sync-code-data workflow on PRs with automatic skip of data download and app release

[Copilot]

Enables the workflow to run on pull requests while automatically skipping expensive operations (data downloads and app releases) that are unnecessary for PR validation.

Changes

• Added pull_request trigger to workflow
• Modified 5 step conditionals to prepend github.event_name != 'pull_request':
  • MT download data (& archive) - skips data download on PRs
  • MT set app release required (or not) - skips release logic on PRs
  • MT assemble release (APK & ABB) - skips app assembly on PRs
  • MT artifact > app-android > APK & ABB - skips artifact upload on PRs
  • MT Publish release (?) - skips app publishing on PRs

PR runs perform code sync and validation (parse current/next, list changes) without downloading fresh data or building releases.

# Before
if: ${{ github.event.inputs.skip-download-data == 'false' }}

# After
if: ${{ github.event_name != 'pull_request' && github.event.inputs.skip-download-data == 'false' }}

Code Review

This pull request successfully enables the mt-sync-code-data workflow to run on pull requests, correctly skipping expensive operations like data downloads and app releases. The introduction of a composite action actions/setup is a great improvement for modularity and maintainability. I've found one issue with the logic for scheduled runs which could prevent data from being downloaded. My review includes a suggestion to fix this.
