docs: add git config user.* to commit successfully

[bearomorphism]

Fixes #1876

Verified the solution by running vhs docs/images/commit.tape, and the generated /tmp/commitizen-demo folder is with correct git log (with a commit authored by you@example.com)

Pull request overview

This PR fixes the broken commit.gif generation in the documentation by adding git user configuration commands to the VHS tape file. The issue occurred because GitHub Actions environments don't have git user.name and user.email configured by default, causing commits to fail during the automated screenshot generation process.

Changes:

• Added git config user.email and git config user.name commands to the commit.tape VHS recording script

Yes, this PR fixes the issue. The problem wasn't caught earlier because I had global git config set locally, so it always worked on my machine.

Thanks @bearomorphism for the fix!

I've tested it with clean environment and confirmed it works correctly.
