[FIX] account: position of tax edit pencil on bills

The commit https://github.com/odoo/odoo/pull/128376 fixed an issue related to rtl languages,
but at the cost of the pencil position.
By making the span containing the value a display: block the pencil could no longer be placed
on the side of the value and was instead pushed on top.

This small fix will just place the pencil inside the span, in order to get it back aside the amount.
