Add auto fix commands for JS and CSS lint errors

[isuke01]

The Story is similar as my other PHPCS QOL change.

I see people adds it project to project, I do it too.
The problem is also people tend to name command differently project-to-project.

I think it is good to have it added by default and standarize command.

In this case I used one that I mostly used by Kevin and Jøgen and I stared to use the same notation.

We can agree on any other notation, but I wish to have standarized one.

Fix duplication

I agree that a unified fix-related command makes sense, this needs a few adjustments before it can be merged;

Currently there is a lint command that will run all commands prefixed with lint:, this means it would also run the fix commands, which I suspect would not be intentional.

Perhaps adding fix: as a prefix instead of a suffix would make more sense? We could then more easily also have a fix:lint shared command to run all fixers, and it does not compete with the existing linting structure.

Also curious how this applies alongside the lint-staged command that's there, they serve different use cases, but the same purpose 🤔
