Check Pull Request Title

A GitHub action that checks that a PR title matches a regex patter.

Could be used for:

• Enforcing any commit convention.
• Enforcing including a Jira ticket reference in the title.
• Enforcing using Conventional Commits.

This is intended to be used with the Autosquash action so that squashed commit messages follow a convention.
