Bugzilla

### Beta/Release Uplift Approval Request
* **User impact if declined**: We regularly update `search-telemetry-v2.json` via Remote Settings. If we update entries in that file with component `type`'s not present in the schema, `browser/components/search/test/unit/test_search_telemetry_config_validation.js` will fail. 

Part of this change will loosen the restriction from a list of allowable strings to a general regular expression to avoid having to do these future uplifts.
* **Is this code covered by automated tests?**: Yes
* **Has the fix been verified in Nightly?**: No
* **Needs manual test from QE?**: No
* **If yes, steps to reproduce**: 
* **List of other uplifts needed**: bug 1878818
* **Risk to taking this patch**: Low
* **Why is the change risky/not risky? (and alternatives if risky)**: Changing the schema should only affect `browser/components/search/test/unit/test_search_telemetry_config_validation.js`.
* **String changes made/needed**: 
* **Is Android affected?**: Yes
