Describe the bug / provide steps to reproduce it

Recently Zed switched to pylsp as the default linter. I am finding it runs much slower that pyright ran and I have had to change my settings to use pyright specifically instead of the default.

The gif below uses default zed settings for python linting as of 2024-11-22.

(It seems to lint better so I am happy with the switch otherwise.)

Environment

Zed: v0.162.5 (Zed)
OS: macOS 15.1.1
Memory: 16 GiB
Architecture: aarch64

If applicable, add mockups / screenshots to help explain present your vision of the feature

What is the source of the diagnostic in this video (this should be the prefix of it's contents)? As in, is it mypy or something else? I'm pretty positive that some of the issues with pylsp performance would have to be either fixed via our config (e.g. we should probably use dmypy instead of mypy) or upstream.
