Specified a minimum version of TypeScript required using
typesVersions
field. If the version is below, the TS compiler directs the compiler to use a typings file calledtypescript-not-supported.ts
which contains a single string which will be logged as a syntax error in the TS compiler, and provide useful error info to the user.Following user suggestions here: microsoft/TypeScript#32166
Fixes #8837
I chose 4.5 because due to the issue above we know that the SDK requires at least 4.5. I'm not sure if there are any other TS features we are using that require an even higher version (in a product or bundle that user wasn't using) but we can increase it if we discover any.
