[jaeger] make curl image configurable

[FieteO]

What this PR does

This PR makes the curl image that is used for elasticsearch configurable and changes it to not use a latest tag:

helm template --set provisionDataStore.elasticsearch=true . | grep curlimages
          image: curlimages/curl:8.11.1
          image: curlimages/curl:8.11.1

The tag is configurable via

images:
  curl: "curlimages/curl:8.11.1"

I am not sure that is the best location in the values.yaml file. I am open for suggestions.
