Feature: Make sure the version in use is stable

[abacao]

According to this issue link, Microsoft Teams can choose some users to be on some testing group.

As we in linux have so much barriers to overcome, I think it would be great if we could always be on a stable environment.

According to the issue, there is a way to force the use of a stable web version of msteams.

For now, changing the link to the following works:
https://teams.microsoft.com/v2/?ring=general
This forces teams to use the pool of regular mainstream users that doesn't get any experimental features such as the one that's currently breaking everything...

Can/should this be the default for this snap?
If not, is it possible to create some documentation that allows the user to change it if wanted/needed?

Hi @abacao, you should be able to just use the url config option for that. Let me know if it doesn't work.
