fixes https://github.com/TryGhost/Toolbox/issues/532
- we should protect against failures entering `main` which could be
avoided by running a quick unit test beforehand
- this reintroduces Lerna as it supports parallelisation and `--since`,
to run linting and unit tests on packages that have changed since
upstream
- our use-case for this is to ensure that people don't push to
`main` without running linting, as this can block CI from passing
until the linting issue is resolved
- however, it can become annoying to run linting on non-main branches,
especially when you just want to WIP some changes without caring for
linting
- generally speaking, anyone who creates commits on a non-main branch is
going to open them as a PR, so linting is run anyway
- this commit get the branch name and only runs linting if we're on
`main`

- we've seen an issue with `lint-staged` in the Admin package because it
doesn't pick up the lint-todo file, so it incorrectly flags linting
issues that we're ignoring
- this is happening because it runs the command from cwd, where the lint
exclusion file does not exist
- thankfully, `lint-staged` has `--relative` which will run the command
from the directory where the command is defined in config, so `ghost/admin`
in our case, and that means the lint file is present and picked up
- up until this commit, git hooks were only used by a handful of people
because they were a pain:
- they'd only be set up when you did `yarn setup`
- the existing hooks ran `yarn lint` on all projects, which was
incredibly slow
- as a result, not many of us actually had them enabled, but this would
cause issues in CI because people were pushing un-linted commits
- other JS projects tend to use husky to automate the git hook setup and
lint-staged to speed up linting on changed files
- this commit switches to using them both
- `lint-staged` only runs `eslint` on staged JS files that are about to
be committed - if there's a linting error, it will stop the commit
- I've configured the pre-commit hook to successfully exit in CI because we
don't want to run pre-commit hooks right now
- this means we can remove Grunt - yay!

- The hook file has to be executable to be triggered in the pre-push stage:
hint: The '.git/hooks/pre-push' hook was ignored because it's not set as executable.

- While developing locally it's common to commit small WIP changes which might contain linting errors. Having the check done once on a pre-push phase gives enoght protection from pushing out broken code and reduces frustration when developing locally

- Naz has broken the main too many times - it's time to stop the atrocities.
- Having a lint check as a pre-commit hook will make it really hard commiting code with linting errors
refs #8235
Usage:
- for existing development setups: `grunt symlink` (will create the pre-commit symlink)
- for fresh development setups: `npm run init` (symlinking happens as part of the typical set up)
- ✨ Added pre-commit hook to handle submodules
- Checks to see if there are any submodules about to be committed
- Output matches closely to `git st` to make it easy to read
- Requires interaction from the committer to accept that this really should be committed
- ✨ Use grunt symlink to register githooks
- Grunt symlink will make a link to the pre-commit hook
- It ONLY does this if there isn't already a pre-commit hook, so won't overwrite anything
- It does this as part of npm run init, not grunt init, because a release repo would NEVER want this
- This is a dev tool, that configures the repo for development
