lsp/python: Temporarily report just a singular workspace folder instead of all of the roots (#35243)

Temporarily fixes #29133

Co-authored-by: Cole <cole@zed.dev>

Release Notes:

- python: Zed now reports a slightly different set of workspace folders
for Python projects to work around quirks in handling of multi-lsp
projects with virtual environment. This behavior will be revisited in a
near future.
