Describe the bug

The :checkhealth reports that ruff-lsp is unavailable. It is true that ruff-lsp does not have a configuration file like prettier, however it is configured and seems to be working (it formats the py file.

============================================================================== conform: require("conform.health").check()

Expected Behavior
