added test cases for flags with empty string value

[MagicMarka]

Loosen validation to allow empty string in string-valued flag variations was added in this ticker https://linear.app/eppo/issue/FF-3794/loosen-validation-to-allow-empty-string-in-string-valued-flag

Some typing and object property errors in here. Look at test-case-new-user-onboarding-flag.json for an example string-valued flag test file.

Also, you can try this out locally by checking out the common javascript SDK and then dropping this file in the test data directory so it is run. That is the development pattern I use.

Thanks for working through this one with me.
You will need to rebase with main before the js-client tests will run and pass properly (to pick up my workflow fix)

I reran the test suites but the js-client seems to be stuck using the test workflow from before my fix. If you push changes to your branch, it should reload the workflow files from the remote repositories

I dug into the multiplatform test failing and found an issue in the test file that I suppose only that SDK is checking. I made a suggested change in the test file with the expected structure for you.

Thanks again! Please make sure the test suites are all passing before merging.

nit:add newline please.

I tracked down the cause of react-native and js-client tests failing
It's an issue with a truthy check in the test harness. SDK is doing the right thing. Fixes to the tests are here:

Eppo-exp/react-native-sdk#72
Eppo-exp/js-client-sdk#165

Thanks for iterating! Assuming these pass when you drop them into an SDK and run all the tests cases, I'd say we are good 🚀
