feat: net8 support

1. Updated the version of the 'actions/setup-dotnet' action from v3 to v3.2.0 in 'build.yml' and 'codeql-analysis.yml'. (line 1)
2. Updated the 'dotnet-version' parameter in both files to include multiple versions of .NET, including 8.0.100, 7.0.403, and 6.x. (line 2)
3. Changes were made to ensure compatibility with different versions of .NET and to improve the overall functionality of the workflows.
