[REM] accounting: remove page about purchase receipts

Sale and purchase receipts aren't really useful anymore. However, they
are left in the app for corner cases and to avoid upgrade issues. Since
this page is already deprecated, it is best to remove it.

-Purchase receipts
-=================
-
-**Purchase Receipts** are not invoices but rather confirmations of received payments, such as a
-ticket or a receipt.
-
-This feature is meant to be used when you pay directly with your company's money for an expense.
-**Vendor Bills**, on the other hand, are recorded when an invoice is issued to you and that the
-amount is first credited on a debt account before a later payment reconciliation.
-
-.. note::
-   Expenses paid by employees can be managed with **Odoo Expenses**, an app dedicated to the
-   approval of such expenses and the payments management. Click :doc:`here
-   </applications/finance/expenses>` for more information on how to use Odoo Expenses.
