[Bug]: "Share with me via Nextcloud" buttons arte broken in settings and in the wild

[strugee]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

The "Share with me via Nextcloud" button found at /settings/user/sharing doesn't work, because its target links to the "sharing" section of nextcloud.com's Features page.

Steps to reproduce

1. Visit /settings/user/sharing
2. Click "add to your website"
3. Click the blue "Share with me via Nextcloud" button

Alternately:

1. Visit https://strugee.net/contact
2. Click the blue "Share with me via Nextcloud" button

Expected behavior

I'm shown how to create a federated share, or something like that. Not really sure what was here before.

I'm imagining it would be something like https://matrix.to/.

Additional info

Filing against nextcloud/core because I couldn't find a repo for the website.

Note that it's not enough to just fix the settings page - these buttons are presumably all over the place in the wild.
