feat: Support Net 9.0

Description 📝

• Purpose: Support NET 9
• Approach: Adopt NET 9 in sample projects and update packages acordingly
• Raygun.Blazor: Make .NET 9 compatible #61

Type of change

• New feature (non-breaking change which adds functionality)

Updates

To support both apps targetting Net 8.0 and Net 9.0, the following projects are set to target both frameworks, and define dependencies for either the two:

• These projects support both targets net8.0 and net9.0:
  • Raygun.Blazor
  • Raygun.Blazor.Server
  • Raygun.Blazor.WebAssembly

As well, the corresponding samples and test projects have been updated

• Sample projects migrated to use net9.0:
• Raygun.Samples.Blazor.Server
• Raygun.Samples.Blazor.WebAssembly
• Test projects migrated to use net9.0:
  • Raygun.Tests.Blazor
  • Raygun.Tests.Blazor.Server

To align with Raygun 4 MAUI, the MAUI projects are still on net8.0:

• These projects are still using net8.0 frameworks:
  • Raygun.Blazor.Maui uses net8.0-android, net8.0-ios etc.
  • Raygun.Samples.Blazor.Maui remains in net8.0

Test plan 🧪

• Build and unit tests work
• Run the sample projects

Dependency constraints depend on the target framework. When targeting net 9.0, versions can be from >= 9.0.0 to <10.0.0

Looks good to me
