ty does not respect VIRTUAL_ENV and TY_PYTHON environment variable #2794
Description
Summary
Hello,
Trying to run ty but it's refusing to use the venv.
The venv is correctly set with the VIRTUAL_ENV variable.
Trying to set TY_PYTHON to specify the location but that doesn't work either.
(note that I filled a similar ticket in uv nearly 2 years ago and you added a UV_PYTHON environment variable to uv).
related: the doc could use some clarification whether the python setting should be a python executable or a directory or something else (both seem to work).
$ ty check tests/unit
ty failed
Cause: Failed to discover local Python environment
Cause: Invalid `VIRTUAL_ENV` environment variable `/turbo/rmorotti/pyenvs/man.core.311`: points to a broken venv with no pyvenv.cfg file
Cause: No such file or directory (os error 2)
$ ty check --python=$VIRTUAL_ENV tests/unit
Checking ------------------------------------------------------------ 634/893 files
...
$ ty check --python=$VIRTUAL_ENV/bin/python3 tests/unit
Checking ------------------------------------------------------------ 682/893 files
$ TY_PYTHON=$VIRTUAL_ENV ty check tests/unit
ty failed
Cause: Failed to discover local Python environment

Cheers.
