Many dead links to government resources

[nickrsan]

We can move these to be archive links in the nearterm, but I think we should reconsider the CoC more broadly - keep the many good parts of this one and expand it to also include many of the elements in this other one: https://github.com/randsleadershipslack/documents-and-resources/blob/main/code-of-conduct.md

The broken links reported to me are:
The GSA anti-harassment policy

All of the Legal Considerations links at the bottom:
Laws enforced by the EEOC
Types of discrimination prohibited by law
New and proposed regulations
