docs update: pagination slot

[OlegKlochkov]

Proposed Changes

• Add b-table's pagination slot to docs

[wesdevpro]

@OlegKlochkov I thought this was already in the docs. And I don't believe there is a prop called pagination for the table component

[kikuomax]

@wesdevpro I think this PR is relevant, because pagination is not a prop but a named slot that BTable actually has:

buefy/src/components/table/Table.vue

Lines 23 to 44 in fb73795

	<slot name="pagination">
	<b-table-pagination
	v-bind="$attrs"
	:per-page="perPage"
	:paginated="paginated"
	:rounded="paginationRounded"
	:icon-pack="iconPack"
	:total="newDataTotal"
	:current-page.sync="newCurrentPage"
	:aria-next-label="ariaNextLabel"
	:aria-previous-label="ariaPreviousLabel"
	:aria-page-label="ariaPageLabel"
	:aria-current-label="ariaCurrentLabel"
	@page-change="(event) => $emit('page-change', event)"
	:page-input="pageInput"
	:pagination-order="paginationOrder"
	:page-input-position="pageInputPosition"
	:debounce-page-input="debouncePageInput"
	>
	<slot name="top-left"/>
	</b-table-pagination>
	</slot>

I do see that now on line 23.
