Remove :skip-ssrf-check? true from prepare-organization-sso-provider so
SSRF protection is active when validating organization SSO configs.
The endpoint is already protected by shared-key authentication
(admin-console), but enabling SSRF protection prevents potential misuse
of internal network resources if the shared key were ever compromised
(defense-in-depth).
Add test prepare-organization-sso-provider-does-not-skip-ssrf-check to
verify the SSRF check is not skipped.
