Enforce stricter restrictions of version response

Response to CTAP AuthenticatorGetInfo command contains supported versions.
Previously, the CTAP spec did not specify exactly which strings to expect
for versions, but with the new spec, only 2 -- "FIDO_2_0" and "U2F_V_2"
are expected to be present as versions.
