Git doc/issue urls inside of pyproject.toml

[Julien00859]

In case you give the URL to a repository that is not hosted on github (e.g. git web https://git.drlazor.be/?p=example;a=summary) then the issue/documentation URLs inside of pyproject.toml are wrong:

[project.urls]
Documentation = "https://git.drlazor.be/?p=example;a=summary/wiki"
Issue = "https://git.drlazor.be/?p=example;a=summary/issues"
Repository = "https://git.drlazor.be/?p=example;a=summary"

We should make a map of all online git hosting services with their issue/wiki URL and not fill the issue/doc inside of pyproject.toml when the service is unknown
