[antonio-rmrz]

Resolves https://jira.corp.adobe.com/browse/MWPW-184913
QA Checklist: https://wiki.corp.adobe.com/display/adobedotcom/M@S+Engineering+QA+Use+Cases

• Automatically links GitHub PRs to Jira tickets when a PR is opened
• Extracts Jira ticket IDs (e.g., MWPW-12345) from PR title or branch name
• Verifies the ticket exists in Jira before creating the link
• Creates a remote link in Jira pointing back to the PR with format [repo] PR #Number: Title
• Skips gracefully if no ticket ID found or link already exists

Example:

Test URLs: N/A

looks great! i wonder to what extent while we are at it, we shouldn't fail the PR if the title doesn't fit a certain pattern.
of course, there are those that should be dealt with #506 but probably better if that one would have JIRA ticket as well to track effort there as well
