Cyber resilience SIG page

We need to add a SIG page to https://orcwg.org/ under the About menu titled Cyber Resilience SIG (the current About page will become the first menu item under About titled ORC Working Group).

Proposed content: https://docs.google.com/document/d/1QnIvt87puaGLndT5nBGFo9MVurp0BWBRYzctBIwfhI4/edit?usp=sharing

We will need a headshot of the two SIG leads.
