OpenSSF best practices badge

[planetf1]

The openssf best practices badge can demonstrate a project follows best practice.

Unlike the scorecard, this badge has specific levels: bronze, silver, gold. Rather than automated checks it is a self-assessment where a project can explain their approach to a particular aspect.

In previous work I undertook, we achieved silver (nearly gold) on our egeria project

Originally opened as PQCA TAC issue #45 . We discussed on the TAC, and felt it was down to individual projects to decide whether to adopt, and at what pace. If oqs were to adopt we could feedback to pqca.

No deadline/timeline but as noted by @baentsch in the original issue, this is related to #1 github.com/orgs/open-quantum-safe/discussions/1892

Note: Apologies I won't be able to make TSC/further meetings this month to discuss
