Updgrade from v6 -> v8. TimeZoneInfo.ConvertTimeBySystemTimeZoneId: No coercion operator is defined between types 'NodaTime.LocalDateTime' and 'System.Nullable`1[System.DateTime]'

Issue:
We are attempting to upgrade our projects from Dotnet 6 to Dotnet 8. When using TimeZoneInfo.ConvertTimeBySystemTimeZoneId in a DbContext that is setup to .UseNodaTime(), an SQL query can no longer be generated. No coercion operator is defined between types 'NodaTime.LocalDateTime' and 'System.Nullable'1[System.DateTime]'
Our project is a mixed DateTime/NodaTime as we incrementally move away from NodaTime. Thankfully the functionality that uses TimeZoneInfo.ConvertTimeBySystemTimeZoneId is not widespread. So our work around is to use NodaTime.Instant and it's related .InZone(...) call. But we would expect DateTime focused calls to still function, even when .UseNodaTime() is used.
