fix(ci): update dotnet-version from 9.0.x to 10.0.x (#94)

The global.json requires SDK 10.0.103 but the workflow only installed
9.0.x. The runner's pre-installed 10.0.102 is one patch behind, causing
`dotnet workload install wasm-tools` to fail with "compatible .NET SDK
was not found". Installing 10.0.x ensures the latest 10.0 SDK is
available to satisfy the global.json requirement.
