Add SQL Server 2022 to test matrix

[pounard]

Because I'm actually experiencing this bug: microsoft/mssql-docker#868 and really, I don't want to downgrade my kernel, I think we need to add SQL Server 2022 in the test matrix, that would allow people with (not so) bleeding edge Linux distros to run the tests.

Moreover, it's probably a good thing to simply test it also.

In fact, problem is still up for 2022 as well: we need the CU12 to be released (latest is still CU11): https://learn.microsoft.com/en-us/troubleshoot/sql/releases/sqlserver-2022/build-versions

I guess I just have to wait. At least we're not all annoyed (only archlinux, and all the latest fedora release as far as I know).
