adding support for webhook-admission validation

[sepulworld]

#145

[sepulworld]

I considered adding

{{- if (Capabilities.APIVersions.Has "cert-manager.io/v1") }}

Up to you though... it is sort of nice but if people are using ArgoCD (using helm template) these Capabilities checks don't play nice in charts. I say leave it out and just document cert-manager is required if you want to use it.

looks like helm-docs needs to be run again. Or maybe it's difference in versions?

Additionally, what will happen if cert isn't present but value is set to true? pyrra will skip webhook creation?

Seems like CI passes now, all that's needed is to run helm-docs because variables in values.yaml and readme doesn't match

It would skip the creation if we used

{{- if (Capabilities.APIVersions.Has "cert-manager.io/v1") }}

I say we leverage this API capability check built into Helm. I will add a new commit

Might be worth bumping chart version as well, so it will release automatically after merge
