Development: Fix deprecated configuration in jest.config.js

[aplr]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Motivation and Context

When running tests, the following warning appeared, often several times, which clutters the test output:

ts-jest[ts-jest-transformer] (WARN) Define `ts-jest` config under `globals` is deprecated. Please do
transform: {
    <transform_regex>: ['ts-jest', { /* ts-jest config goes here in Jest */ }],
},

Description

As suggested by the warning and in the docs for jest-preset-angular, the ts-jest options were now moved from the global ts-jest configuration to the jest-preset-angular transform.
