problem when vim plugin repo uri contains @

[teto]

Describe the bug

It's not possible to add an url with a @ in vim-plugin-names.
For instance I tried
pkgs/applications/editors/vim/plugins/update.py --proc=10 --debug DEBUG --github-token=$GITHUB_TOKEN --add [email protected]:yorickpeterse/nvim-pqf.git
which triggered

Instantiating github repo ggandor/lightspeed.nvim
Instantiating github repo gibiansky/vim-textobj-haskell
Instantiating github repo gioele/vim-autoswap
Traceback (most recent call last):

    repo = make_repo(uri.strip(), branch.strip(), alias)

    repo = RepoGitHub(res[0], res[1], branch, alias)
IndexError: list index out of range

vim-plugin-names expects owner/repo@branch and it splits on @. I passed [email protected]:yorickpeterse/nvim-pqf.git and so splitting on @ doesn't work here.

Additional context

The format of the file itself seems limiting see #136248

In the end I use nix-build -A vimPlugins.nvim-bqf since it seems more active but this issue could concern other plugins.

Metadata

Please run nix-shell -p nix-info --run "nix-info -m" and paste the result.

nvim-pqf and bqf are not similar after all, I would rather use pqf
