[Feature] Return WebLN provider info to website

Feature description

Currently there is no way to detect which WebLN provider one uses. Alby could return some information to the website which the website can use to display provider specific information. E.g. a button with "Pay with Alby" or "Pay with [Alby icon]"

Describe the solution

relevant information:

• providerName
• providerURL?
• iconURL
