The values.yaml on the datahub chart points to a old image

[fixwhat]

Hello,

I was implementing geonetwork-ui using the Helm charts and realize that the current values.yaml is refering to a 'master' branch. 'Master ' is a very old image and it does not carry the wc-embedder.html file. So the chart works but the advanced web components do not.

I changed from:

image:
  repository: geonetwork/geonetwork-ui-datahub
  tag: master

to

image:
  repository: geonetwork/geonetwork-ui-datahub
  tag: latest

And everything worked.
