podAnnotations is incorrectly passed to deployment

[lkoniecz]

Proposal

Add removal of all leading and trailing whitespace, including newlines via {{- -}} here https://github.com/wiremock/helm-charts/blob/master/charts/wiremock/templates/_helpers.tpl#L71 and parse with toYaml

{{- toYaml .Values.podAnnotations | nindent 0 -}}

othewise the tenplate is not rendered when podAnnotation is provided

Reproduction steps

add

podAnnotations:
  aa: bb

to values.yaml, fire

❯ helm template .      
Error: YAML parse error on wiremock/templates/deployment.yaml: error converting YAML to JSON: yaml: line 23: could not find expected ':'

Use --debug flag to render out invalid YAML
