Try setting RollForward on FSharpLint.Console to latestMajor

refs #687, whereby it appears to not be able to process .NET 7 or 8 projects when running on .NET 6, and always using the latest version seems to help.

It looks like the current roll foward behaviour was added for #519 to fix issues where only a newer version than the tool was built with is available, but this change would make it just use the latest all the time (so for example, if you have 6 and 8 installed, then it will use 8 all the time).
