Fixing incorect project name and add tested version

[Voriaz]

Hello,

I successfully migrated from Gitlab 1.17.1 to Gitea 1.22.1, So I'm adding this to README.md.

Also, I propose to replace project.name with project.path in the code. The main reason for this is that in Gitlab you can create a project with a name containing spaces and specify a different name for repo url/path. This is not possible in Gitea as project name and path must be the same. So, I propose to use project.path instead of project.name as Gitea repo name in order to keep the same url for Gitea repo.

Thanks,

A.
