Inject venv environment via the toolchain (#36576)

Instead of manually constructing the venv we now ask the python
toolchain for the relevant information, unifying the approach of vent
inspection

Fixes https://github.com/zed-industries/zed/issues/27350

Release Notes:

- Improved the detection of python virtual environments for terminals
and tasks in remote projects.
