Add an error message for unsupported .NET versions in Linux

[chynesNR]

If the Profiler tries to attach to a process running under an unsupported version of .NET (i.e. older than Core 3.1), the log only contains an error code without context

[Info ] 2022-11-09 15:24:55 Logger initialized.
[Trace] 2022-11-09 15:24:55 New Relic .NET CoreCLR Agent
[Error] 2022-11-09 15:24:55 0x7fc4e6afc77c

I see code in the Profiler to log that the platform is unsupported, so it's not clear why that's not working.

Acceptance Criteria

The log should clearly indicate what the failure is.
