docs: Remove all traces of "identity.pub" from docs

"identity.pub" is referenced multiple times in CRDs and docs. This secret
is however never used in any place. Instead, the public key is derived from
the "identity" private key.

This commit/PR removes all traces of "identity.pub" from v1beta2 CRDs and
docs.
