 The filters `next_posts_link_attributes` and
 `previous_posts_link_attributes` were applying to the incorrect posts
 navigation links.



 **Are you using either the latest version of WordPress, or the latest
 development version?**

 Website is using WordPress core v5.9.3.

 **What steps should be taken to consistently reproduce the problem?**

 I added a filter in my theme, using the filters
 `next_posts_link_attributes` and `previous_posts_link_attributes`, and
 they were applying to the incorrect posts navigation links. The filter
 `next_posts_link_attributes` was applying to the previous nav link and
 vice versa.

 **In case it's relevant to the ticket, what is the expected output or
 result? What did you see instead?**

 On further investigation, I found the bug in `wp-includes/link-
 template.php` in the function definition for `get_the_posts_navigation()`,
 line 2788 and 2789, where the incorrect functions are being used for
 `$next_link` and `$prev_link`.
