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.

The InnerSource Flywheel

Issue にリンクされている InnerSource Ambassadors パターンから始め、背景を理解するために参照されている InnerSource Flywheel の講演を確認してください。議論では、Capital One をまだ実装済みの例として扱うべきではないと明示されているため、そもそも Capital One を掲載すべきかどうかを判断してください。done は、明確化された判断と、承認された場合はそれに対応するパターンの更新とします。
