nit: update OpenSSL-Strategy.md

[brodybits]

OpenSSL-Strategy.md seems to have some old info no longer needed. For example, I just raised PR #1007 to fix a statement regarding OpenSSL and Node.js 10.x.

P.S. After raising this issue I discovered that Node.js started using a quictls fork of OpenSSL in nodejs/node#37601. I would appreciate if this info would be in OpenSSL-Strategy.md.

Thanks to mhdawson for the response to this issue and PR #1007.

@danbev I know you've been keeping up to date on the OpenSSL 3.X front maybe you can take a look at doing a bigger update on: https://github.com/nodejs/TSC/blob/main/OpenSSL-Strategy.md
