Add Revolt (rev2) keyboard

[nietaki]

Adding the Revolt rev2 keyboard. I dogfooded the functionality and the default keymap while working on this PR.

The layout for QMK configurator has also been tweaked to resemble the keyboard:

Thank you for the review, @waffle87 🙇

The reasoning behind the suggestions makes sense to me, and I didn't even realise how much you can configure in info/keyboard.json!

[nietaki]

Thanks, I didn't spot that in the docs either!

I made sure I didn't mess up the mask (F11 gets picked up by the OS instead of the tester):

Suggested change

	#define MATRIX_MASKED

For future reference (for myself, but maybe also others): The data/mappings/info_config.hjson file looks like the source of truth for all the values that can/should be configured in keyboard.json instead of config.h

edit: that file and data/schemas/keyboard.jsonschema

Thank you, @zvecr, should be all better now.

Thoughts on me making a separate PR to update the docs with the keyboard.json approaches of some of the things I ran into (custom keycodes for example)?

There's not too many examples of some of them in the codebase either, without the docs being updated y'all will probably spend a lot of time giving the same PR feedback for newly added keyboards....
