Support of .Net Core 3.0 for Lamar.Microsoft.DependencyInjection

[vhatsura]

I used Lamar.Microsoft.DependencyInjection from .net core 3.0 preview7 (this is possible because 3.0.0 is higher than 3.0.0-previewX) and it works perfectly without any issues. I believe the upper bound can be update to include 3.0 https://github.com/JasperFx/lamar/blob/24127a21d0729ec15d48ff02d8998b69d93668c1/src/Lamar.Microsoft.DependencyInjection/Lamar.Microsoft.DependencyInjection.csproj#L23-L25

This should now be resolved.
