Mxdev

- Nothing changed yet.

- Fix 42: deprecated use of `pkg_resoures` to load entry points and parse requirements.
This enables mxdev to work on Python 3.12, where `pkg_resources` is no longer installed by default in virtual_envs.

- Breaking: Remove `--pre` on sources from generated `requirements-mxdev.txt`.
Usually it is not needed any longer, at least withy pip 23.x.
This is a breaking change if you rely on the `--pre` option being present in the generated file.
Now the `--pre` option should be added to `pip install` when the generated file is used.
This change enables the use of the generated file with the alternative pip replacement `uv`.
