Add Capital One as a Known Instance for the InnerSource Ambassador

pattern: InnerSource Ambassadors

@spier This does a great job at capturing all of the elements for IS ambassadors.

To answer your questions, yes it's a good description of what we are doing. Some additions I would suggest are:
a) where you say "are enthusiastic about IS", I would add "and ideally have experience using open source practices".
b) add info on 'what's in it for the ambassadors'. For example, it provides opportunity and topic for ambassadors to reach out and engage beyond their immediate teams. it provides opportunity for learning, enhancing influence, problem-solving, and communication skills, opportunity to share their expertise and passion in a structured way, and to network with like-minded enthusiasts.

re: whether Capital One is an org that has implemented the pattern:
I would not list Capital One yet. What is described in the pattern is our intent, but we are not yet an example of one that has fully implemented the pattern.

For extra reference also see this talk from the ISC Summit 2024:
The InnerSource Flywheel

Comienza con el patrón InnerSource Ambassadors enlazado en el issue y revisa la charla InnerSource Flywheel referenciada para obtener contexto. Resuelve si Capital One debería aparecer en absoluto, ya que en la discusión se dice explícitamente que todavía no debe tratarse como un ejemplo implementado; done debería consistir en una decisión aclarada y la correspondiente actualización del patrón, si se aprueba.
