fix: Change the value of pageOffset when enabling server side pagination (#36056)

## Description
Fixed issue #36022 where incorrect data is displayed when navigating to
the previous page after reaching the last page with fewer items in the
table during server-side pagination enabled by using `props.pageSize`
instead of `props.tableData?.length`.


Fix:

Replaced `props.tableData?.length` with `props.pageSize` to ensure
consistent data display when navigating between pages, especially when
dealing with the last page that has fewer items than the pageSize.


Fixes #36022

## Automation

/ok-to-test tags="@tag.Table"
