chore: remove husky 🪓🐶

[regisb]

We remove husky, which is triggering pre-push git hooks, including running "npm lint". This is causing failures when building Docker images, because "npm clean-install --omit=dev" automatically triggers "npm prepare", which attemps to run "husky". But husky is not listed in the build dependencies, only in devDependencies. As a consequence, package installation is failing with the following error:

	14.13 > @edx/[email protected] prepare
14.13 > husky install
14.13
14.15 sh: 1: husky: not found
