Describe the bug
Debian 13 (trixie) has been released yesterday.
How can we update or install Regolith Desktop with Debian 13?
Error when updating:
E: The repository 'https://archive.regolith-desktop.com/debian/stable trixie Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
To Reproduce
Perform an upgrade from Debian 12 (bookworm) to Debian 13 (trixie).
Expected behavior
No error when using the APT repository for Debian 13.
Screenshots
The docs explain how to install for Debian Testing and Debian Bookworm, but no mention of Debian Trixie:

Configuration file(s)
/etc/apt/sources.list.d/regolith.list:
deb [arch=amd64 signed-by=/usr/share/keyrings/regolith-archive-keyring.gpg] https://archive.regolith-desktop.com/debian/stable trixie v3.3
Installation Details
- Regolith Install Stage: 4.8.0
- Regolith Version: 4.8.0
- Host OS: Debian
Additional context
The upgrade guide of Debian also states that we should prefer deb822 over the old format:
APT is moving to a different format for configuring where it downloads packages from. The files /etc/apt/sources.list and *.list files in /etc/apt/sources.list.d/ are replaced by files still in that directory but with names ending in .sources, using the new, more readable (deb822 style) format. For details see sources.list(5). Examples of APT configurations in these notes will be given in the new deb822 format.
