fix: use pull_request_target for PR title linting

[dlevy-msft-sql]

Summary

Fixes 'Resource not accessible by integration' error for fork PRs.

Root Cause

• Fork PRs get read-only GITHUB_TOKEN with the pull_request trigger
• amannn/action-semantic-pull-request needs access to PR metadata which fails with insufficient permissions

Fix

• Use pull_request_target trigger which runs in base repo context
• This is safe because we do NOT checkout or execute any PR code
• Added statuses: write permission for the action to post status checks

Testing

• This workflow change will be tested by any subsequent fork PR

Pull request overview

This PR adds a new GitHub workflow to enforce Conventional Commits format for pull request titles. The workflow uses pull_request_target trigger to ensure it works correctly for fork PRs by running in the base repository's context with appropriate permissions.

Changes:

• Added new workflow file .github/workflows/pr-title-lint.yml that validates PR titles using amannn/action-semantic-pull-request action

Consider adding configuration to customize the Conventional Commits validation if the project has specific requirements. The action supports several configuration options (e.g., custom types, scopes, subject pattern) that can be specified with 'with:' parameters.

For example, if the project wants to enforce specific commit types (feat, fix, docs, etc.) or require scopes, these can be configured. Review the action's documentation to determine if the default configuration meets the project's needs.

The 'synchronize' event type is unnecessary for PR title linting. This event triggers when new commits are pushed to the PR, but the PR title doesn't change during synchronization. This will cause the workflow to run unnecessarily on every commit push.

Consider removing 'synchronize' from the types list to avoid redundant workflow runs. The workflow should only run when the PR title can actually change: 'opened', 'edited', and 'reopened'.

Suggested change

	types: [opened, edited, synchronize, reopened]
	types: [opened, edited, reopened]
