Add generic comment on PR script

[domoscargin]

This is the MVP for a script to comment on PRs.

It can be passed the Github context, a marker string to identify which comment to target, and the content of the comment. The idea is to get this functionality into the codebase soon, then work on improvements such as:

• Creating the "stats" workspace to contain this script and other performance monitoring stuff
• Adding the ability to use workflow parameter inputs to define A and B inputs for diffing

Closes #3545

Cheers for bringing that in and hunting the types to make it all proper 😊 Spotted a little issue with the last comment automatically added on this PR and got a little suggestion for the API.

From having dug a little more into this, do you think there could be a way to add automated tests to the commentOnPr as well or would we have to maintain our own mocks of Github's API and responses for that?
