Description

Hi there, thanks for this extension set! I'm a very happy user.

I noticed what I think is a MagicLink bug in zizmor's documentation, appearing with zizmorcore/zizmor#415: it looks like user/.github#num doesn't appear to recognize user/.github as the user/repo slug, and instead sees it as {default_user}/github#num.

For example, nextcloud/.github#477 is included here and gets linked incorrectly to https://github.com/woodruffw/github/issues/477, instead of https://github.com/nextcloud/.github/issues/477.

Some additional details here: zizmorcore/zizmor#415

Minimal Reproduction

1. Use user/.github#num as a MagicLink
2. Observe that the link is to {default_user}/github#num instead of user/.github#num
