Add paths and outcomes to update-gradle-wrapper action output

[Copilot]

This PR enhances the update-gradle-wrapper action to provide detailed path-level information about update outcomes, making it easier to track which specific Gradle wrappers succeeded or failed during updates.

Changes Made

Enhanced Action Outputs

• Added updated-paths: Newline-separated list of paths where Gradle wrappers were successfully updated
• Added failed-paths: Newline-separated list of paths where Gradle wrapper updates failed
• Maintained backward compatibility with existing found-count and updated-count outputs

Improved Test Workflow Display

The test workflow now displays results with intuitive emoji indicators:

• ✅ Green checkmarks for successfully updated wrappers
• ❌ Red X marks for failed wrapper updates
• Shows the specific path for each outcome

Example Output

Before this change, the test workflow only showed summary counts:

Update Results:
  - Found: 3 wrapper(s)
  - Updated: 2 wrapper(s)

After this change, it provides detailed feedback:

Update Results:
  - Found: 3 wrapper(s)
  - Updated: 2 wrapper(s)

📋 Detailed Results:
✅ Successfully updated wrappers:
  ✅ /path/to/project1
  ✅ /path/to/project2
❌ Failed to update wrappers:
  ❌ /path/to/project3

Technical Implementation

The shell script now tracks two arrays:

• UPDATED_PATHS[] for successful updates
• FAILED_PATHS[] for failed updates (already existed, now exposed as output)

These are serialized as newline-separated strings in GitHub Actions outputs using the proper multiline format with EOF delimiters, making them easy to parse in workflows while maintaining compatibility with shell scripting.

Testing

• ✅ Verified with successful update scenarios
• ✅ Tested with mixed success/failure scenarios
• ✅ Confirmed backward compatibility
• ✅ Validated YAML syntax
• ✅ Fixed multiline output format issue

Fixes

• Fix Add paths and outcomes to action output #9 - Add paths and outcomes to action output
• Fix multiline output format error in GitHub Actions

Fixes #9.

Fixed the multiline output format issue. The error was caused by an incorrect format when writing multiline values to $GITHUB_OUTPUT. GitHub Actions requires EOF delimiters for multiline outputs. Fixed in commit 28f3537.
