Observable Documentation: broken link to Promise

[Chealer]

RxJS version: This bug is not in the RxJS product.

Code to reproduce: This does not report a behavioral bug.

Expected behavior: This does not report a behavioral bug.

Actual behavior: This does not report a behavioral bug.

Additional information:
The introduction of the Observable page contains a table with a link labelled Promise, which brings to https://developer.mozilla.org/en-US/docs/Mozilla/JavaScript_code_modules/Promise.jsm/Promise
That URL unfortunately yields a 404 error now. It should visibly be replaced with:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

By the way, that table is quite confusing. It would help to clarify what it contains.
