[IMP] accounting/taxcloud: how to set up default account for new taxes

New taxes generated by the TaxCloud integration are by default created without an income or an expense account specified. By default, the journal items corresponding to these taxes therefore end up in the default income account, which is usually the 'Sales' account, when they should in fact go to the 'Tax Payable' account. Because these taxes are automatically generated on-the-fly, the user is usually not able to manually specify the Tax Payable account before the journal items are posted, leading to incorrect accounting entries which then need to be manually repaired through the use of miscellaneous operations.

To solve this issue, our video on TaxCloud integration (https://www.youtube.com/watch?v=JE-NeRNIWeU&t=616s) tells us to create a User-Defined Default for the account field of the tax.repartition.line model. This sets the default account with which new taxes are created. However, this information is missing from the documentation.

This PR brings the documentation up-to-date by explaining how to create this User-Defined Default that specifies the correct Tax Payable account.

+* For each one of your companies that uses TaxCloud, it might be necessary to create a 
+  **User-Defined Default** so that the new taxes generated by the TaxCloud integration are created 
+  with the correct Tax Payable account:
+  
+.. warning::
+   A User-Defined Default impacts all records at creation.  It means that **every** new tax will be 
+   set up to record income in the specified Tax Payable account, unless the tax is manually edited
+   to specify a different income account (or there exists another User-Defined Default that takes 
+   precedence).
+
+* In :menuselection:`Accounting --> Configuration --> Chart of Accounts`, select the Tax Payable
+  account for the company. Take note of the account's ``id`` in the URL string.
