fix: Updating the pageId in the reconnect modal for Gsheets authorization (#26125)

## Description

Updating `pageId` in the reconnect modal for Gsheets authorization. It
was taking the `pageId` of the old delete page for authorization from
the query params. This has been fixed by using props instead if its
inside reconnect modal.
