Describe the bug

Links to the User Handbook and Developer handbook are broken on the handbook's index page.

While on handbook's index page:

Expected behavior
click on the User Handbook link - https://wordpress.org/gutenberg/handbook/users/readme/
and user is redirected to https://wordpress.org/gutenberg/handbook/readme/

click on the Developer handbook - https://wordpress.org/gutenberg/handbook/designers-developers/readme/
and user is redirected to https://wordpress.org/gutenberg/handbook/readme/

Have to guess this is related to the caching issue mentioned in Slack today. Seems our changes to the manifest aren’t being picked up by the auto syncing.

Brought this up in today’s #meta chat; awaiting more info from that team.

#12411 partially addresses this, although we also now have a bunch of 404s we need to clean up.

The link to the Users Handbook is still broken as of this morning, which seems like a critical issue to fix before Thursday: https://wordpress.org/gutenberg/handbook/users/

@greatislander The users handbook link will be removed, hopefully in #12585. We aren't going to store the users handbook on GitHub for the moment, it will be stored inside of HelpHub on WordPress.org once that's live, hopefully in the next few days. Once it's live we will link to it again in the handbook; we're just not sure yet what the final URL for HelpHub will be so we can't link to it quite yet.

Would recommend following the #docs channel in WP Slack for more up-to-date info on this :)

These 404s should be largely resolved now, so I'm going to close this out. If we find specific issues we can get PRs opened to resolve them! Thanks for the report <3
