Can we make Husky an optional install?

### What do you want and why?

I was unable to fix the "command not found" problem with Husky. Until I uninstalled it, I was unable to make a git commit.

### Possible implementation(s)

I'm not sure if it's possible without removing it, but it would it nice if it didn't interfere with anything for people who are not interested in it.

### Additional context

As a new blitz user, Husky and node-gyp gave me headaches. A lot of people would have simply just given up and used Nextjs instead. I strongly feel that it hinders new adopters of Blitz.
