Unable to setup PKI infrastructure, error: cnpg-mutating-webhook-configuration not found

[donchev7]

Hi,

When deploying the helm chart with mutating webhook disabled:

webhook:
  mutating:
    create: false

I get an error:

{"level":"error","ts":"2024-07-30T13:33:16Z","logger":"setup","msg":"unable to setup PKI infrastructure","error":"mutatingwebhookconfigurations.admissionregistration.k8s.io \"cnpg-mutating-webhook-configuration\" not found","stacktrace":"github.com/cloudnative-pg/cloudnative-pg/pkg/management/log.(*logger).Error\n\tpkg/management/log/log.go:125\ngithub.com/cloudnative-pg/cloudnative-pg/internal/cmd/manager/controller.ensurePKI\n\tinternal/cmd/manager/controller/controller.go:380\ngithub.com/cloudnative-pg/cloudnative-pg/internal/cmd/manager/controller.RunController\n\tinternal/cmd/manager/controller/controller.go:222\ngithub.com/cloudnative-pg/cloudnative-pg/internal/cmd/manager/controller.NewCmd.func1\n\tinternal/cmd/manager/controller/cmd.go:40\ngithub.com/spf13/cobra.(*Command).execute\n\tpkg/mod/github.com/spf13/[email protected]/command.go:983\ngithub.com/spf13/cobra.(*Command).ExecuteC\n\tpkg/mod/github.com/spf13/[email protected]/command.go:1115\ngithub.com/spf13/cobra.(*Command).Execute\n\tpkg/mod/github.com/spf13/[email protected]/command.go:1039\nmain.main\n\tcmd/manager/main.go:66\nruntime.main\n\t/opt/hostedtoolcache/go/1.22.4/x64/src/runtime/proc.go:271"}

I believe this is due to the helm chart not properly configuring the certificate directory when mutating webhooks are disabled.

Should I create a PR for this?
