Added TuxSuite repos to Debian extrepo

Thanks for the talk at DebConf23 - TuxMake with Debian. After watching it, I took the initiative to add TuxSuite repos to extrepo, a tool that helps configuring external repositories on Debian in a secure manner.

Here are the merge requests to extrepo-data:

with extrepo installed it can be enabled with:

sudo extrepo enable tuxsuite

Then tuxsuite can be installed as usual:

sudo apt update
sudo apt install tuxsuite

And if the URL or the GPG key has changed, once updated in the extrepo-data repository, it can be easily updated with:

 sudo extrepo update tuxsuite
