fix: tests on iOS 17

[crleona]

Summary

This updated CI to run on the latest versions of MacOS/Xcode.

Running the tests locally with the latest Xcode results in a few failures, so I've fixed the following:

• Use sorted key output for JSON, as iOS 17+ uses a more secure dictionary type that randomizes key order
• Use strict URL parsing as the URL(string:) default behavior has changed in iOS 17
• Clean up testFilterAndEnrichmentPlugin results so that events aren't duplicated between runs (this does not appear to be an issue on CI, only while running locally). (@yuhao900914, can this test just use an in-memory store instead?)

Can this test just use an in-memory store instead? Yes, which memory it's using doesn't matter.
