Add IDAES Solvers to Mac; Update to Ubuntu 22.04

[mrmundt]

Fixes NA

Summary/Motivation:

We did not used to download the IDAES-ext solvers/libs for OSX because they were unavailable and/or built without HSL. I am fairly certain that is not true anymore, so this adds those solvers into our jobs.

NOTE: When I ran this on my branch, it passes for osx/3.12, and the coverage goes up by ~8%.

Changes proposed in this PR:

• Add IDAES-ext solvers to OSX on GHA
• Update Linux to ubuntu-2204 (we were on 2004)
