Fine-tuning of 0501bbd62e.
Now that `company_id` is present in the header, the XPath of the
provider form view defined in the `website_payment` module puts the
field `website_id` in the wrong place.
This commit moves the field where it belongs.
Part-of: odoo/odoo#99846
Changing the name of model payment.acquirer to payment.provider
and everything that it touches. It is technically incorrect to
use the term "acquirer" for systems that only provide a service
of payment.
After this commit the model payment.acquirer and all related to
it will be renamed to payment.provider.
