Microsoft.Extensions.Logging.ProviderAliasAttribute: Better move to Microsoft.Extensions.Logging.Abstractions?

[SetTrend]

If I'm not mistaken, the ProviderAliasAttribute class should rather be defined in the Microsoft.Extensions.Logging.Abstractions package than in the Microsoft.Extensions.Logging package.

Defining a new logging provider doesn't need anything beyond the Microsoft.Extensions.Logging.Abstractions package — except for the ProviderAliasAttribute.

Being required to include the Microsoft.Extensions.Logging package instead of the Microsoft.Extensions.Logging.Abstractions package adds an unnecessary attack surface and dependencies, I think.
