…le Upgrade Flyout) (elastic#210377)

**Partially addresses:** elastic#205645

## Summary

This PR implements Frontend integration tests from the [upgrading prebuilt rules one-by-one with preview test plan](https://github.com/elastic/kibana/blob/main/x-pack/solutions/security/plugins/security_solution/docs/testing/test_plans/detection_response/prebuilt_rules/prebuilt_rule_upgrade_with_preview.md).

## Details

This PR add Jest integration tests (`@kbn/test/jest_integration` preset) for Rule Upgrade Flyout. Test scenarios are described in [upgrading prebuilt rules one-by-one with preview test plan](https://github.com/elastic/kibana/blob/main/x-pack/solutions/security/plugins/security_solution/docs/testing/test_plans/detection_response/prebuilt_rules/prebuilt_rule_upgrade_with_preview.md).

Tests cover each `diffable rule` field separately to guarantee visibility on broken functionality.

`esql_query` and `threat_mapping` fields were skipped due to mocking difficulties.

### Tests setup

- Rules Management page is used as the root component to test functionality in integration
- HTTP responses are mocked via mocking return values from `Kibana.http.fetch()` method
- Test scenarios are the same for each diffable rule field and moved out to reusable utility functions
