build: remove unused deps and babel-jest related deps

[ghost]

Description

This PR removes the unused deps.
Also this removes babel-jest related deps and configs which is unnecessary.

Motivation and Context

No need to use babel.

ts-jest by default does NOT use Babel. But you may want to use it, especially if your code rely on Babel plugins to make some transformations. ts-jest can call the BabelJest processor once TypeScript has transformed the source into JavaScript.
