fix: Docs needed Camel case feature gate names

[hawksight]

On upgrading to 1.13.1 I tried to use the examples in the documentation. However I got the following errors:

E1017 13:05:38.038480       1 main.go:39] "cert-manager: error executing command" err="failed to set feature gates from initial flags-based config: unrecognized feature gate: experimentalGatewayAPISupport"
E1017 13:08:16.019948       1 main.go:35] "cert-manager: error executing command" err="failed to set feature gates from initial flags-based config: unrecognized feature gate: additionalCertificateOutputFormats"

Tackling this I just needed to capitalise the first letters, which puts the config inline with command like --extraArgs options.
