Update GHC support in INSTALL.md

The GHC version in CI has been updated to 9.2.8. This version is also used to build the official releases (e.g. the upcoming 2023.07). Versions 9.4 and 9.6 are known to compile.  Added version 9.2 as recommendation. The point release (.8 at time of writing) is omitted to avoid having to update it.
