Modifying output options due to Aspire target change

- Remove DefaultName as now file is always manifest.json
- Added DefaultPath which is where it will be created
- Changed temporary file to use temppath + manifest.json naming

This is due to changes in Aspire Preview 4+ for the apphost and requires those versions to work in this new manner.
