Broken Link to Discontinued API Service

[Sunonymous]

The live page for Working with JSONP contains a link in the first paragraph to an official page about the YQL (Yahoo Query Language). The link no longer works. After a bit of digging, it was seen that Yahoo discontinued that API service in early 2019. As an example of working with JSONP, the code may be fine to leave as-is, though it could be better to remove the link mentioned. If the code snippet stays the same, perhaps a note could be included to explain that the service is no longer in operation.

The file in this repository containing the broken link may be found here.

Please let me know if the formatting of this issue could be improved in any way, as this is the first issue I have ever opened. Thank you!
