When trying to send a demo peppol invoice,
a user gets an error about the missing recipient bank.
The user then needs to set the invoice back to draft,
create the bank, save changes, before being able to send the invoice via Peppol.
To make the demo process smoother, this commit adds a `res.partner.bank` record
for every demo company that is eligible for peppol.
However, it can be useful in general, so these are added in the community l10n modules.
