Support for eslint-plugin-jest 29.0.0

[CamilleDrapier]

Since eslint-plugin-jest 29.0.0 was released a short while ago, it would be great if @quasar/quasar-app-extension-testing-unit-jest would allow using it.

I have run a few test with eslint-plugin-jest 29.0.0, and it seems to be generally working, but maybe there is more than just adding the 29.0.0 version to the allowed peer dependencies:

-    "eslint-plugin-jest": "^27.1.3 || ^28.0.0",
+    "eslint-plugin-jest": "^27.1.3 || ^28.0.0 || ^29.0.0",

This should be an easy release, could you draft a PR and test it on the test projects?
You'll need to update eslint-plugin-jest in devDependencies to properly test it

Check out jest:sync:invoke and similar commands in the relevant test projects
See https://github.com/quasarframework/quasar-testing/blob/dev/packages/unit-jest/README.md#testing-the-ae
