.NET 10 Support

I recently updated a C# project to use the new .NET 10 SDK, but my CodeQL workflow started throwing an error on analysis:

> **Error**: Encountered a fatal error while running "/opt/hostedtoolcache/CodeQL/2.23.3/x64/codeql/codeql database finalize --finalize-dataset --threads=4 --ram=14581 /home/runner/work/_temp/codeql_databases/csharp". Exit code was 32 and last log line was: CodeQL detected code written in C# but could not process any of it. For more information, review our troubleshooting guide at https://gh.io/troubleshooting-code-scanning/no-source-code-seen-during-build . See the logs for more details.

I see in the [Supported Languages documentation](https://codeql.github.com/docs/codeql-overview/supported-languages-and-frameworks/) that .NET 10 is not yet listed. Is that truly the issue, and if so is there a timeline for support?

Example public workflow: https://github.com/microsoft/healthcare-shared-components/actions/runs/19305417788/job/55211454683?pr=1301

Start with the Supported Languages documentation and the linked public workflow, then inspect the CodeQL analysis logs for the .NET 10 failure. Done means confirming the support gap or its cause, enabling successful analysis of the example C# project, and updating the relevant support documentation if needed.
