Viewing external profiles via URL fails

[csolisr]

Describe the bug

When attempting to directly view an external account profile via URL (in the form https://social.example.net/users/$NNNNNNNN), the display fails. Viewing it indirectly does display the information, but reloading the tab fails

Context

• Hardware: x86 computer at home
• YunoHost version: 11.1.0.2
• I have access to my server: Through SSH, webadmin, direct access
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
  • If yes, please explain: I have tested this issue with both the stable and testing branches of Pleroma for YunoHost.
• Using, or trying to install package version/branch: 2.4.4

Steps to reproduce

1. Go to your profile
2. Click on any of your follower's profiles that is hosted in another instance, this should open a URL on the form https://social.example.net/users/$NNNNNNNN and let you display the profile information.
3. Copy that URL and open it in a new tab. A JSON error stating "not found" will appear.
4. Return to the original tab and reload it. The same JSON error will appear.

Expected behavior

The profile information should be able to load regardless of where was it opened from.

Furthermore: removing the "$" sign from the URL does allow displaying the profile information properly.
