Update PyPi package registry to use project.urls from pyproject.toml

[satr-cowi]

Description

At the moment a link only seems to appear in the pypi package registry for setup.cfg files with a url field, which is translated to a Home-page metadata field. I believe this bit of meta-data has been deprecated recently: https://packaging.python.org/en/latest/specifications/core-metadata/#home-page

I believe the issue may be related to this line (but not fully sure):

gitea/routers/api/packages/pypi/pypi.go

Line 142 in 9882917

projectURL := ctx.Req.FormValue("home_page")

Ideally links would appear in a similar way to that in pypi (Where the [project.urls] table can take homepage, documentation, tracker etc.)

The current documentation on what metadata is available and how it is used could also be heavily improved.

If it is the case that we are using deprecated metadata to get the home page URL (to me this looks to be the case), then I agree that we should use something else to get this URL. What we should do is:

• Use the Project-URL metadata (see here)
• Since Project-URL can be defined multiple times (e.g a URL for its bug tracker, another for its project board, etc.), we look for one with the label homepage (this is after we normalize the label; see here for "well-known project URLs")
• Use that as the URL for the homepage
• If we couldn't find one with a normalized label of homepage, use the empty string (as we do already)

I'll see if I can implement something like this today

Hi guys, thanks for getting this implemented so quickly!

Not an urgent one, but would there be interest in the future in adding links for other project URLs too similar to pypi?
