PR Comment and Update Action

A GitHub action that will comment on the relevant open PR with a file contents when a commit is pushed. If the action has already commented on the PR, an update to the previous comment will be made instead.

Based off of PR Comment Action by Alexander Matheson.

Usage

• Requires the GITHUB_TOKEN secret.
• Requires the comment's artifact in the msg parameter.
• Requires a comment prefix in the prefix parameter. Comments with the prefix will be subsequently updated if the action is run again.
• Supports push and pull_request event types.
