BUG: kubernetes-ingress: Remove unneeded tpl function

[mecampbellsoup]

Since tpl expects a string, passing an unqouted, fully-numeric image tag value results in a helm templating error, e.g.:

INFO[0000] install.go:214: [debug] Original chart version: ""
install.go:231: [debug] CHART PATH:

This PR is not going to be accepted as it would break things. tpl is intended to render .Chart.AppVersion in controller.image.tag (https://github.com/haproxytech/helm-charts/blob/e1e93595153b326992bd4f2a3d54cb7af48d08aa/kubernetes-ingress/values.yaml#L64C10-L64C35) with a value from Helm that's set in Chart.yaml as appVersion (https://github.com/haproxytech/helm-charts/blob/e1e93595153b326992bd4f2a3d54cb7af48d08aa/kubernetes-ingress/Chart.yaml#L20C1-L20C11) so that we don't hardcode latest version in values.yaml, but in Chart.yaml as it is common practice and a preferred way of doing things.
