[tests] Jest may incorrectly detect open handles when running the tests

[JanEbbing]

Describe the bug
See fix in jest: jestjs/jest#13414
Unfortunately, this version of Jest (29.2+) requires Node 14.

To Reproduce
In the console, running tests may give a warning similar to the following

$ node_modules/.bin/jest --detectOpenHandles --no-cache tests/
 PASS  tests/general.test.ts
 PASS  tests/glossary.test.ts (24.288 s)
 PASS  tests/translateDocument.test.ts (31.975 s)
 PASS  tests/translateText.test.ts (6.858 s)

Test Suites: 4 passed, 4 total
Tests:       11 skipped, 50 passed, 61 total
Snapshots:   0 total
Time:        66.442 s
Ran all test suites matching /tests\//i.

Jest has detected the following 2 open handles potentially keeping Jest from exiting:

Expected behavior
Tests should run without throwing warnings.
