refactor: update to .NET SDK version 10.0.300

[vbreuss]

This pull request updates the extension method signatures in Mockolate to improve nullability handling and simplify type constraints. The changes make the extension methods more flexible by allowing nullable types and optional builder parameters, and by removing unnecessary notnull constraints.

Nullability and Type Constraint Updates

• All extension methods in Mockolate.Setup and Mockolate.Verify now accept nullable generic type arguments (e.g., T?, T1?, etc.) and the builder parameters themselves are now nullable (e.g., IPropertySetupReturnWhenBuilder<T?>?). This change increases the flexibility of the API and improves compatibility with nullable reference types.
• The where T : notnull and similar type constraints have been removed from all relevant extension methods, further relaxing the requirements on generic parameters.

Pull request overview

Bumps the .NET SDK pin from 10.0.201 to 10.0.300 and refreshes the public-API baseline snapshots (Mockolate_netstandard2.0.txt, Mockolate_net8.0.txt, Mockolate_net10.0.txt) to match the new SDK's API-extractor rendering of extension declarations. The previous output emitted extension<T>(... <T> setup) where T : notnull; the new SDK renders the same declarations as extension<T>(... <T?>? setup) (constraint removed, generic args and parameter annotated nullable). No source code is changed — only the SDK version and the expected-output text files used by the API compatibility tests.

Changes:

• Update global.json SDK to 10.0.300.
• Regenerate API baseline files for netstandard2.0, net8.0, and net10.0 to match the new compiler/API-extractor formatting of extension blocks.
