fix(baseline): hide status from async-clipboard subfeatures

[LeoMcA]

Summary

See: web-platform-dx/web-features#495

Problem

Showing the Baseline widget for the overall async-clipboard feature group on some pages that belong to that group has confused users, as there appears to be a discrepancy between the "not baseline" status, and an all-green bcd table, e.g. on https://developer.mozilla.org/en-US/docs/Web/API/ClipboardEvent/clipboardData

Solution

While we find a solution to this wider problem upstream, hide the widget on the problematic pages. For now that's, all clipboard pages other than the overview pages:

• https://developer.mozilla.org/en-US/docs/Web/API/Clipboard_API
• https://developer.mozilla.org/en-US/docs/Web/API/Clipboard

Screenshots

As an example, there's many more pages affected:

How did you test this change?

Visited, and still saw a "limited availability" status:

• http://localhost:3000/en-US/docs/Web/API/Clipboard_API
• http://localhost:3000/en-US/docs/Web/API/Clipboard

Visited, and now saw no status:

• http://localhost:3000/en-US/docs/Web/API/Clipboard/read
• http://localhost:3000/en-US/docs/Web/API/Clipboard/readText
• http://localhost:3000/en-US/docs/Web/API/Clipboard/write
• http://localhost:3000/en-US/docs/Web/API/Clipboard/writeText
• http://localhost:3000/en-US/docs/Web/API/ClipboardEvent
• http://localhost:3000/en-US/docs/Web/API/ClipboardEvent/ClipboardEvent
• http://localhost:3000/en-US/docs/Web/API/ClipboardEvent/clipboardData
• http://localhost:3000/en-US/docs/Web/API/Navigator/clipboard
• etc.
