See https://codeberg.org/forgejo/discussions/issues/164 for the rationale and discussion of this change. Everything related to the `go-git` dependency is dropped (Only a single instance is left in a test file to test for an XSS, it requires crafting an commit that Git itself refuses to craft). `_gogit` files have been removed entirely, `go:build: !gogit` is removed, `XXX_nogogit.go` files either have been renamed or had their code being merged into the `XXX.go` file.
