chore: remove husky 🪓🐶

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
