Michael Sproul a1befd89aa Update openssl for CVE-2022-0778 (#3095) ...

## Issue Addressed

Fix the `cargo-audit` failure for the recent openssl bug involving parsing of untrusted certificates (CVE-2022-0778).

## Additional Info

Lighthouse loads remote certificates in the following cases:

* When connecting to an eth1 node (`--eth1-endpoints`).
* When connecting to a beacon node from the VC (`--beacon-nodes`).
* When connecting to a beacon node for checkpoint sync (`--checkpoint-sync-url`).

In all of these cases we are already placing a lot of trust in the server at the other end, however due to the scope for MITM attacks we are still potentially vulnerable. E.g. an ISP could inject an invalid certificate for the remote host which would cause Lighthouse to hang indefinitely.
