Add link to user documentation at https://docs.pypi.org/ in footer or other prominent location

What's the problem this feature will solve?

I could not find a link to the Warehouse or PyPI user documentation anywhere. There is an FAQ, but it did not answer my question, specifically how to get unverified details to be verified for my package.

Describe the solution you'd like

Add a link to the user documentation at https://docs.pypi.org/ in the footer or other prominent location.

Additional context

I eventually found the user documentation as follows.

1. Scrolled to the footer to look for the right link under Help.
2. User guide: wrong link.
3. FAQ: nope again.
4. Contribute on GitHub: Aha! Now we're getting somewhere!
5. Searched for the term Unverified details. Bingo!
6. Navigated to https://github.com/pypi/warehouse/blob/main/docs/user/project_metadata.md?plain=1
7. Read the relevant docs. Much rejoicing!
8. Saw a README.md in the same directory, and read it to finally find the URL to the PyPI User Documentation as https://docs.pypi.org/
9. Viewed and searched the HTML source of PyPI for https://docs.pypi.org/ to ensure it wasn't hidden somewhere that I missed. Came up empty.

Thank you for your consideration.

Thanks for the request @stevepiercy! I agree the user docs should be linked more prominently -- at the moment there are a couple of links on the /help/ page, but these are not easily discoverable.

I'll look into where better we can link this.
