Make Test Data a folder reference

[kean]

This PR starts preparing WordPressTests for move to Tests/KeystoneTests. It contains only one change: add "Test Data" as a folder reference.

To test:

Regression Notes

1. Potential unintended areas of impact

2. What I did to test those areas of impact (or what existing automated tests I relied on)

3. What automated tests I added (or what prevented me from doing so)

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Testing checklist:

• WordPress.com sites and self-hosted Jetpack sites.
• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)

Looking good.

Before	After

Two non blocking nitpicks:

• What do you think of removing the space in the folder name to be more scripts-friendly? From "Test Data" to "TestData"/"Test-Data" or even just "Data" or "Inputs"
• Do we need the "Dashboard" subfolder? I mean it's handy to group those four files in there, but it makes the setup inconsistent. If we have "Dashboard", then we should also have "Activity-Log", "App-Review-Prompt".

I'll update the folder structure in the upcoming PR when I move the files to Tests/KeystoneTests.
