* Refactor solution file from .sln to .slnx format and update related documentation and scripts

- Created new Aspire.slnx file with updated project structure.
- Updated contributing and usage documentation to reference Aspire.slnx.
- Modified build scripts to use Aspire.slnx instead of Aspire.sln.
- Adjusted project template configuration to exclude both .sln and .slnx files.
- Updated startvs.cmd to default to Aspire.slnx when no solution is specified.

* Update local VS Code settings
