Remove babel-jest from devDependencies (#1247)

## Description:

Tiny change, remove babel-jest from devDependencies. 

(This PR was intented to remove more from package-lock.json. So we could
get rid of two npm warnings about deprecated glob version, and
unsupported inflight from the underlying test-exclude dependency which
is part of the babel-plugin-istanbul dependency.

But then i found out that more packages have babel-jest and
babel-plugin-istanbul as dependencies themselves.

However, we don't use babel-jest directly. Normally it is used as a
transformer for tests, but we use ts-jest for that in jest.config.ts.
And we don't use it anywhere else. That's why we don't need it in
devdependencies, even if other packages still install it.
