v4.0.0: Drop support for PowerShell <7.4 and logging overhaul
PowerShell 7.2 LTS and 7.3 are now past end-of-support and are now unsupported.
This is an incompatible API change so we're bumping the major version.
Please update to PowerShell 7.4 LTS going forward.
This release contains a logging overhaul which purposely removes our
dependency on Serilog and should lead to improved stability with
PowerShell 5.1 (by avoiding a major GAC assembly conflict).
