Add first/last page or page jump navigation to contributor activity pagination

[tusharaddweb]

The contribution history pagination on WordPress.org profiles currently only provides "Previous" and "Next" navigation along with the current page indicator (e.g. "Page 5 of 240").

For contributors with a large contribution history, navigating to a specific page or the last page requires repeatedly clicking the Next button, which is inefficient.

Consider adding one or more of the following:

• First and Last page buttons
• A "Go to page" input
• Numbered page links

This would improve usability for profiles with many pages of activity.
