pytest --version less verbose by default #7128
Description
Currently pytest --version shows something like:
$ pytest --version
This is pytest version 5.4.2, imported from d:\projects\pytest\src\pytest\__init__.py
setuptools registered plugins:
hypothesis-4.36.0 at d:\projects\pytest\.env36\lib\site-packages\hypothesis\extra\pytestplugin.py
pytest-forked-1.1.1 at d:\projects\pytest\.env36\lib\site-packages\pytest_forked\__init__.py
pytest-xdist-1.31.0 at d:\projects\pytest\.env36\lib\site-packages\xdist\plugin.py
pytest-xdist-1.31.0 at d:\projects\pytest\.env36\lib\site-packages\xdist\looponfail.py
We should follow other tools (black, pre-commit, Python), where --version shows only the tool version, while --version --version shows more information.
