add um_utils docs

[james-bruten-mo]

PR Summary

Code Reviewer: @yaswant

It's been pointed out that the um_utils docs aren't included in the gh-pages deployment. They're built by the workflow but not deployed. This corrects that.
It also changes the workflow to only upload the artifact if this is a push to main.

The artifact is still uploaded from ./mule/docs/build/html so I am not sure how that would work! You probably forgot to replace ./mule/docs/build/html with .github/files in the upload-pages-artifact step?

we need to upload:

somewhere (we have the built docs for both mule and um_utils that will be uploaded)
├── index.html
├── mule
└── um_utils

Thanks Yash - might have made more sense if I'd remembered to update the artifact upload path!

But agree we don't need to store the index.html file, so updated that

Looks good.
