CI: Filter distutils Version warnings from pytest output

[rraymondgh]

CI logs are full of distutils Version classes are deprecated from older versions of pandas and numpy. This then means that real warnings that should be cleaned up are missed. Add to pyproject.toml to suppress DeprecationWarning from pandas and numpy that match this text.

Moved other pytest settings from setup.cfg into pyproject.toml

Thanks, this is a good idea!

Practical comment: we already have some pytest configuration in setup.cfg, so let's keep it all together in that file (nowadays pytest also supports using pyproject.toml as a place to put configuration, so if putting it in another file, we should eventually move to use that one I think)

+1 to that now that #2512 is mergeable.

+1 to that now that #2512 is mergeable.

I noted that #2512 has been merged. Have now put config into pyproject.toml and moved other pytest config from setup.cfg

This seems to work, thanks!
