Add pre-commit support

[codingjoe]

Hello again 👋,

I guess I don't need to explain pre-commit very long.

Adding support for a new linter, like msgcheck is fairly simple. The repo just needs a config file and maybe a line of documentation. That's it.

I'd be happy to contribute it :)

Best
Joe

Hello @codingjoe,

You want to make msgcheck available in pre-commit for other projects?
