Can we have better error messages for TS5097: non '.ts' extension used in a query or operation ext import

[Martinsos]

This is the message I got:

This was caused by me specifying .ts extension in operation ext import:

action createFile {
  fn: import { createFile } from "@src/file-upload/operations.ts",
  entities: [User, File]
}

Once I removed that .ts, error went away.

But it would be hard for others to figure out this was the cause, the ext import in main.wasp.

@sodic suggest forbidding any extension in ext imports or somehow processing them by us so we allow all of them.

[Martinsos]

Or maybe we turn on this compiler flag, if it has no bad effects.

Sending this back to triage, this is quite an annoying error.
