fix(jest): vulnerability fix

[Andras-Csanyi]

PR summary

This PR brings a major update for jest (v27), and covers the consequences of it.

• using done has been removed from unit tests
• using done is removed from integration tests, but the methods are not refactored to async
• using done is removed from examples too, and all the examples are refactored to async due to using some custom logic around console.log and console.warn
• integration tests run ok, expect when used account related issues (they might be rotated already), these tests also can manage that when no .env file provided (in this case the test skips execution)
• examples run ok, expect when used account related issues (they might be rotated already so we can't use the account anymore), the examples also can manage that when no .env file provided

Possible follow up tasks:

• refactor integration tests to async from promise
• modify the generated integration tests and examples accordingly
• re-gen example-json files for SDKs

We also have to figure out whether async pattern or promise pattern is the preferred one in the reference.
