fix(ui5-dynamic-page): update header action button tooltip text

[kgogov]

Update message bundle to use "Collapse Header" instead of "Snap Header" for better UX consistency.

Fixes #12617

A little Suggestion

The tooltip text has been updated from "Snap Header" to "Collapse Header" for UX consistency, but the JSDoc comments in DynamicPage.ts still reference the old terminology:

Line 75:

If focus is on the snap header button (arrow button), or on the header itself, once activated, it triggers the associated action (such as snap/expand the header).

Suggestion: Update this to:

If focus is on the collapse header button (arrow button), or on the header itself, once activated, it triggers the associated action (such as collapse/expand the header).

This would make the documentation consistent with the user-facing tooltip text change.

Thanks for the suggestion! I was also considering changing the terminology from "snap" to "collapse" everywhere, including variable names. Honestly, in this specific case, it’s not strictly necessary since the SAPUI5 DynamicPage documentation still uses the term "snap". The change here is mainly for the tooltip text to improve UX clarity — the actual behavior remains the same; we’re just using a synonym for "snap".
