Can I open a PR to remove mdit-py-plugins?

[lukehsiao]

textual never imports mdit_py_plugins anywhere in the codebase. The
package originally came in through markdown-it-py's "plugins" extra,
and PR #6163 replaced that extra with a direct dependency to break a
dependency cycle for bazel users, carrying the unused package along.
The Markdown widget's "gfm-like" preset only needs the "linkify" extra,
which is kept.

Discovered using pyproject-udeps [1].

Would you mind if I opened a PR removing this dependency?
