[.NET]: Emit multiple api-versions in our metadata file for multiple services #9377
Description
We are now supporting the feature to generate multiple services with different api versions into one Azure SDK package.
However, the current meta.json file is limited to support single api version, so we need to extends this support to update meta.json for multiple api versions.
This is a required feature if we want to generate arm compute library from TypeSpec.
Please refer to the discussion in Azure/typespec-azure#3749 for more details.
