fix: allows docs.openedx.org links to open

[saraburns1]

Instructor dashboard -> Reports tab -> Help tab in any of the 3 reports
When you click the Aspects Reference link it opens a new tab and says "docs.openedx.org is blocked"

SDK v0.3.0 sets allow-popups but not allow-popups-to-escape-sandbox, so popups stay inside the sandbox — and a page that sends Cross-Origin-Opener-Policy (docs.openedx.org does) can't load in a sandboxed popup which causes ERR_BLOCKED_BY_RESPONSE.

We need to add allow-popups-to-escape-sandbox to the SDK iframeSandboxExtras
