[DevTools][SearchProfiler] Copy Review

[jloleysens]

After merging this PR: #48795

We need to review new copy introduced under the Screenshots new section. Specifically:

• Profiling...
• Nothing to see here yet.
• Enter a query and press the "Profile" button or provide profile data in the editor

Here is some text I was thinking of. Let me know what you think.

Empty state

No queries to profile
Enter a query, click Profile, and see the results here.

@miukimiu The second second above refers to an action that the user takes in the editor to the left of the panel that contains the message. Do you think we need a left-pointing arrow?

Loading message

Loading query profiles...

Tagging in @miukimiu as she's working on the UI/UX side of Search profiler. See Gail's question above.

@gchaps Thanks for the copy recommendations. They sound great to me!

I suppose updates to any relevant screenshots that may be hanging around can wait until after @miukimiu 's changes.

@gchaps thanks for the copy. Yes, I think the action should be clickable. But I can change that when I bring the UI/UX changes (#49772) and also put a more colorful, happier empty state.

Looks like some copy improvements were made via #51700.
