Replace hooks plugin with native MkDocs 1.4.0 `hooks:` config

[HonkingGoose]

Describe the proposed change(s).

Intro

MkDocs 1.4.0 ¹ has a new hooks: ² config option, which can load in Python scripts. This means we may be able to drop a dependency.

Material for MkDocs does not support this new hooks: config option (yet). I opened an issue to ask for the hooks: option to be supported, see the todo list below.

Todo:

• Wait for the update for mkdocs 1.4.0 to land in our repository
• Wait until we get a version of Material for MkDocs that supports the hooks: feature:
  • squidfunk/mkdocs-material#4420
• Drop mkdocs-simple-hooks dependency from our Pipfile, drop lockfile
• Run pipenv install to get a fresh lockfile
• Drop the mkdocs-simple-hooks lines from the mkdocs.yml file
• Update mkdocs.yml so it uses the new hooks: option
• Run build, test if things keep working

	# Reads the edit_url from the yaml page header and replaces the default one with it
	def on_page_context(context, page, config, **kwargs):
	if 'edit_url' in page.meta:
	page.edit_url = page.meta['edit_url']
	return context
