Pants

How can I check, what's the version of a backend in pants? Specifically I want to check, which `mypy` version it is using.

• For versions 2.22 (currently in pre-release) or newer, it's visible on the docs page <https://www.pantsbuild.org/2.22/reference/subsystems/mypy> or via `pants help mypy`  ("This version of Pants uses `mypy` version 1.4.1 by default")
• For versions 2.21 and earlier, you have to find the relevant section of the built-in lockfile:  e.g. for 2.21.0: <https://github.com/pantsbuild/pants/blob/release_2.21.0/src/python/pants/backend/python/typecheck/mypy/mypy.lock#L138-L150> (also 1.4.1)
