Beyond Identity: Allow SSH Keys and GPG keys that are not issued by the Beyond Identity service to be added to the user profile

Summary

Currently, when the Beyond Identity integration is enabled, only the GPG keys that were issued by the Beyond Identity service can be added to the user profile.

We need to expand this requirement to allow SSH Keys and GPG keys that are not issued to the Beyond Identity service to be added to the user profile. If the key has been issued by the Beyond Identity service, the key can only be added if it has been validated against the user email (as in the current implementation).
