Update dependencies

[cluster]

Description

This PR updates elixir dependencies. It mainly affects phoenix (1.6) and liveview (and refactoring .html.eex or .html.leex files to .html.heex) and using esbuild instead of webpack.

Webpack was used (among others) to convert scss to css, so it's been replaced by dart_sass, as advised here. But unfortunately dart_sass couldn't be used to build the docker image because it's not compatible with alpine, as a workaroung it's using sass installed through npm.

This PR also contains a commit from this PR.

Note: Because git_hooks has been updated, it might be necessary to run mix git_hooks.install in case this error occurs when trying to git push:
