Skip hooks installation when env variable is set

[pantosha]

It's useful to skip git hooks installation when environment variable is set, e.g. SIMPLE_GIT_HOOKS=0

Similar functionality in husky: https://typicode.github.io/husky/guide.html#bypass-hooks

Hi, yep, this would be a nice feature to implement. However, if im not mistaken, you can omit from using git hooks using --no-verify option when you run git commit

Yeah, you can commit via CLI, but in GUI (like Fork) usually it's not really possible

I think this issue can be closed once #96 is made available as a new NPM version 🙏

Should be live in 2.10.0. Thanks @pantosha for the issue and big thanks to the @bhanuprasadcherukuvada for the PR #96
