fix: Update cert-manager to use crds.enabled instead of the deprecated installCRDs option

[kinyat]

What does this PR do?

This is a follow-up to #435.

Instead of changing the option directly, we add a pre-check before setting installCRDs.

If the user has already set the new crds.enabled flag in either values or set, we do not add the deprecated installCRDs option.

This helps prevent breaking changes and allows users to avoid the deprecated installCRDs option.

Update: Follow-up to #443 (review)

I have updated the PR to pump up the version of the cert-manager to the latest minor version.

I have also updated the PR to remove the usage of installCRDs and replaced it with both the new crds.enabled and crds.keep options.

Lets just bump up the version of cert-manager and set crds.enabled instead of installCRDs. We can break compatibility with older versions because we use semantic versioning on the module.

Can you please give it a 2nd look?

I don't recommend hardcoding this. I would suggest to remove this entirely and let helm values decide whether we need to install CRDs or not. This is no different to other ex: aws_load_balancer_controller.

Additionally, I should have the flexibility to choose whether to manage CRDs through the addon or deploy them externally. Would harcoding limits my option to disable CRD ? If it is preferred option, why are we not consistently doing it for other addons.
