CURLOPT_CAINFO.3: polished wording

Browse Source 
Clarify the functionality when built to use Schannel and Secure
Transport and stop calling it the "recommended" or "preferred" way and
instead rather call it the default.

Removed the reference to the ssl comparison table as it isn't necessary.

than supported by nss-pem, because libnssckbi.so also includes information
about distrusted certificates.
(iOS and macOS) If curl is built against Secure Transport, then this
option is supported for backward compatibility with other SSL engines, but it
should not be set. If the option is not set, then curl will use the
certificates in the system and user Keychain to verify the peer, which is the
preferred method of verifying the peer's certificate chain.
(iOS and macOS) When curl uses Secure Transport this option is supported. If
the option is not set, then curl will use the certificates in the system and
user Keychain to verify the peer.
(Schannel) This option is supported for Schannel in Windows 7 or later but we
recommend not using it until Windows 8 since it works better starting then.
Added in libcurl 7.60. This option is supported for backward compatibility
with other SSL engines; instead it is recommended to use Windows' store of
root certificates (the default for Schannel).
If the option is not set, then curl will use the certificates in the Windows'
store of root certificates (the default for Schannel).
The application does not have to keep the string around after setting this
option.
