[DevHub] REST API FAQ: "WordPress support forums" link points to 404

[manhphuc]

Page URL:
https://developer.wordpress.org/rest-api/frequently-asked-questions/

Issue:
The "WordPress support forums" link currently points to the following URL, which returns a 404:

https://wordpress.org/support/topic-tag/rest-api/

This results in a broken link for users trying to access related REST API discussions in the support forums.

Expected result:
The link should point to a valid Support Forums tag page so users can access relevant REST API support topics.

Suggested fix:
Update the link to point to a valid Support Forums tag page, such as:

https://wordpress.org/support/topic-tag/wordpress-rest-api/

This would help ensure users can easily find related discussions and support resources.
