eng/scripts/TypeSpec-Generate-Sdk.ps1

###
# Conventient usage: 
# 1) generate specific language sdk based on current typespec folder
#   ./TypeSpec-Generate-Sdk.ps1 -SdkLanguage {language}
#   e.g. ./TypeSpec-Generate-Sdk.ps1 -SdkLanguage dotnet
# The pre-requisite is the sdk repos path in local machine follows below convention:
# 1). "azure-rest-api-specs" and "sdk-repos" are peer folder under same parent folder
# 2). each sdk language repo is under "sdk-repos" folder, i.e.
#     sdk-repos/azure-sdk-for-net
#     sdk-repos/azure-sdk-for-java
#     sdk-repos/azure-sdk-for-python
#     sdk-repos/azure-sdk-for-js
