Update Rule Blocklist

Remove:

* import/extensions - it does not fail when can not resolve module, uses
  literal value instead
* import/no-absolute-path - does not use module resolution, checks
  whether literal value starts with "/"

Add:

* import/no-restricted-paths - relies on absolutely resolved module
  paths
* node/no-hide-code-modules - relies on module resolution, also
  deprecated
