refactor(auth/sso): rename GetAuthorizationUrl for clarity (#10173)

- Rename `GetAuthorizationUrl` to `GetAuthorizationUrlForSSO`
- Move `GetAuthorizationUrlForSSO` from `sso.resolver.ts` to
`auth.resolver.ts` to avoid the permission guard and let users use an
SSO provider.
- Fix an issue in OIDC guard that breaks the connection if you have
multiple SSO providers + add tests for OIDC guard.
