Add pagination controls to new Releases page

What does this MR do?

Adds pagination controls to the new Apollo Client version of the Releases page (added in !61828 (merged)).

The new component added as part of this MR (releases_pagination_apollo_client.vue) is nearly identical to the existing pagination component (releases_pagination.vue) except that it does not rely on Vuex.

What doesn't this MR do?

This MR does not complete the new Releases page. The sort controls are still missing; these will added in a separate MR before the feature flag is enabled.

Feature flag

The new Releases page is hidden behind a releases_index_apollo_client feature flag, which is disabled by default.
