As a shop owner, I can update the "Customer display name; appears on invoices." of existing subscribers so that invoices can be made out to corrected names should they change over time

Is your feature request related to a problem? Please describe.

Please could the company name of ACME Corp be added to the invoice rather than just Bob Smith please?

Currently the subscriber name used during sign up is what appears on initial and future invoices raised by subscriptions, and cannot be changed within Subscribie.

Describe the solution you'd like
As a shop admin, I can login to my admin dashboard, locate a subscriber and update the Account information name (in stripe refered to as "Customer display name; appears on invoices.) to that which is needed.

Describe alternatives you've considered

Additional context
This requires an update to the Customer record/object in the Stripe api.
