Exclude order and orderby query parameters from canonical URL tags

[jonoaldersonwp]

Requests to URLs like:

• ​https://wordpress.org/plugins/?order=asc
• ​https://wordpress.org/themes/?order=desc
• ​https://wordpress.org/showcase/?order=asc&orderby=title
• ​https://wordpress.org/news/page/13/?orderby=rating
• ​https://jv.wordpress.org/?orderby=menu_order
• ​https://lt.wordpress.org/?orderby=rating/page/3/

... all return canonical URL tags which incorrectly include order and orderby parameters.

In all scenarios, these parameters should be excluded from the canonical URL tag.

This is more prevalent than I thought.

SEO: Canonical: Don't include order and orderby in canonical URLs.

Although the content on the requested URL may differ from that of the canonical, consider it the same page.

Fixes #5256.
