Fix Pagination and Bulk Action Warning Conflict

[im3dabasia]

Trac ticket: https://core.trac.wordpress.org/ticket/62534

Description

This fix compares the initial and current page numbers to differentiate between a bulk action submission and a pagination action. If the page number has changed, it indicates a pagination submission, preventing the bulk action warning from triggering. This restores proper pagination functionality while ensuring the warning only appears for bulk actions when no items are selected.

Looks good beside the suggested change for the comment markup.

The problem that causes manual entry of page 1 not to work was committed in https://core.trac.wordpress.org/changeset/38752; but there's no specific documentation about why that change was made. The props were attributed to @swisspidy, however; so I'm pinging Pascal to see if he remembers anything about exactly what that fix was for.

This change appears to still preserve the desired behavior from the original ticket , while allowing the manually typed page number to work.
