Update liboqs readme to point to oqs-provider instead of deprecated openssl1.1.1 fork [skip ci]

This PR updates the OpenSSL link to point to oqs-provider now that OpenSSL1.1.1 is deprecated.

Maybe wortwhile also removing the pointer to a project no longer actively maintained (openssh) and people not exactly relevant any more (Michele Mosca) pointing to PQSA and/or TSC instead?

(side note: use '[skip ci]' to skip CI; 'skip-ci' doesn't)

Ah, thanks for the tip. :-)

I think this would make a lot of sense. I would probably hold off from removing openssh until the list of projects we will continue supporting/won't continue supporting is finalized.

It wasn't clear to me how involved Michele was behind the scenes, but seeing as I started using/contributing to liboqs ~3 years ago and have never talked to them, I think it's as good a time as any haha. But there might be other reasons they is still listed, so I would defer to @dstebila on that one.

I think it's okay to remove the prominent link to OpenSSH, and I've replaced it with a link to our more general demos project.

This is a good time to revisit that wording, as well as also pop in wording about the Linux Foundation, which I've now done as another commit on this branch.
