Serilog.Sinks.EventLog fails Windows validation in .Net Foundation 4.8.1

[brentbiggs]

Basic functional test failing on PS 5.1, but works with PS 7.3. Other tested serilog.sinks (File, Console) function as expected.

Error seems to be centered around this line: https://github.com/serilog/serilog-sinks-eventlog/blob/dac4ef3e2fa3ce4d389c15f22c7141430791ffb0/src/Serilog.Sinks.EventLog/LoggerConfigurationEventLogExtensions.cs#L70
