## Changes
- Remove DetectInterpreters from DetectExecutable call: python3 or
python should always be on on the PATH. We don't need to detect
non-standard situations like python3.10 is present but python3 is not.
- I moved DetectInterpreters to cmd/labs where it is still used.
This is a follow up to https://github.com/databricks/cli/pull/2034
## Tests
Existing tests.
## Changes
Simplify logic for selecting Python to run when calculating default whl
build command: "python" on Windows and "python3" everywhere.
Python installers from python.org do not install python3.exe. In
virtualenv there is no python3.exe.
## Tests
Added new unit tests to create real venv with uv and simulate activation
by prepending venv/bin to PATH.
## Changes
Make `pydabs/venv_path` optional. When not specified, CLI detects the
Python interpreter using `python.DetectExecutable`, the same way as for
`artifacts`. `python.DetectExecutable` works correctly if a virtual
environment is activated or `python3` is available on PATH through other
means.
Extract the venv detection code from PyDABs into `libs/python/detect`.
This code will be used when we implement the `python/venv_path` section
in `databricks.yml`.
## Tests
Unit tests and manually

This PR adds a few utilities related to Python interpreter detection:
- `python.DetectInterpreters` to detect all Python versions available in
`$PATH` by executing every matched binary name with `--version` flag.
- `python.DetectVirtualEnvPath` to detect if there's any child virtual
environment in `src` directory
- `python.DetectExecutable` to detect if there's python3 installed
either by `which python3` command or by calling
`python.DetectInterpreters().AtLeast("v3.8")`
To be merged after https://github.com/databricks/cli/pull/804, as one of
the steps to get https://github.com/databricks/cli/pull/637 in, as
previously discussed.
