Fix redfish_verify_ca boolean handling in certificate

The code was checking for the string 'False' (capital F), but when jq
extracts a boolean false from JSON, it outputs 'false' (lowercase).
This caused the check to fail, resulting in TLS verification being
enabled even when redfish_verify_ca was set to false in nodes.json.

Fixed by checking for both 'False' and 'false' in both:
- utils.sh: node_map_to_install_config_hosts() function
- ocp_install_env.sh: generate_ocp_host_manifest() function

This ensures that disableCertificateVerification is correctly set to
true when redfish_verify_ca is false, allowing Ironic to connect to
iDRAC Redfish endpoints with self-signed certificates.

Related to PR 1812 which enabled TLS validation for Redfish emulator.
