Simplify documentation with GH action deployment

[piedoom]

Documentation issue

Summary

It is unnecessary to create a personal access token when deploying to GH actions

Proposed solution

I recently learned that secrets.GITHUB_TOKEN is accessible, negating the need to create a personal access token, simplifying several steps + removing potential security issues that come with PATs.

This commit demonstrates my repository works when my previous secrets.TOKEN (which was manually set in secrets) is replaced by secrets.GITHUB_TOKEN, which is automatically set by actions. Fixing this documentation would necessitate removing a few sections regarding PATs.

I believe PATs might only be needed now if you are publishing from a different repo, I'll have to double check.
