Add pre-commit-ci hook

[maresb]

We don't currently have any automatic mechanism for updating the version tags in .pre-commit-config.yaml. I think that we should use https://github.com/marketplace/pre-commit-ci. I think this should be straightforward for @ricardoV94 to enable.

EDIT: Strange... GitHub mangled my initial description, so I had to rewrite the above. 😞

@maresb great! Could you help us with PyMC marketing? pymc-labs/pymc-marketing#476 What else do we need to do to make it work ?

@ricardoV94 @twiecki I think we need to give access to the app from the pymc-labs account right?
