Administration: Fix pagination in categories, tags, and plugins tables.

Fix an issue introduced in [59134] that prevented manual entry of a page number in the pagination input field from navigating pages. Requiring validation of the bulk actions input also impacted other inputs nested in the same form.

Also fixes a pre-existing bug where it was not possible to navigate to page 1 using the input field.

Fixes #62534.
