Documentation update actions

Actual Behaviour

The recent release triggered the relatively recently updated documentation update action but there are some problems with running it.

One of them is that as mentioned in #1085, the two newly released p5.js source files referenced here and here isn't yet available at the time the action is run which caused the URL to return "Not Found" as seen in 589064a and the action did not realised the requested files returned a 404.

The other problem is that the commit created is using my details to created the commit which seemed to be the fallback behaviour of the associated action EndBug/add-and-commit@v4 which is not ideal. The author should probably be something more generic or it could be confusing.

I will be making a quick fix to this process for now to address the current issue but I think a more complete rewrite of the release process is needed. I'll do that as part of GSoD rewrite of the release docs.
