Use lint-staged for pre-commit hook in if-plugins and if

[jmcook1186]

What
Replicate Green-Software-Foundation/if-unofficial-plugins#51 in if and if-plugins repositories

Why
These changes make it easier to develop for IF locally as they prevent the linter from taking unstaged changes into account.

Context
Community cointributor made these changes in the if repository (see Green-Software-Foundation/if-unofficial-plugins#51) now we want the same behaviour to be replicated across the other IF repos.

Prerequisites/resources
none

SoW (scope of work)

• replicate https://github.com/Green-Software-Foundation/if-unofficial-plugins/pull/51/files in if and if-plugins
• test locally

Acceptance criteria

• .husky/pre-commit, .lintstagedrc.js and package.json updated to match https://github.com/Green-Software-Foundation/if-unofficial-plugins/pull/51/files
  - the expected behaviour is
  GIVEN a user is developing a plugin or IF feature int heir local environment
  WHEN they commit changes
  THEN the linter should not reject the commit based on the content of unstaged files

• applied to if and if-pluginsrepositories

• new flow is tested manually by committing a chanmge to a local copy of the repository
