[bitnami/common] add namespaces to extraPodAffinityTerms for affinities

[klamas1]

Fix indentation and namespace handling in affinity helpers

Changes

1. Fixed indentation in common.affinities.pods.hard:

   • namespaces is now at the same level as labelSelector
   • Fixed indentation for common.tplvalues.render from nindent 10 to nindent 8

2. Unified namespace handling in both helpers (soft and hard):

   • Current namespace is automatically added in the base rule via {{ .context.Release.Namespace }}
   • Current namespace is also automatically added in additional rules via {{ $.context.Release.Namespace }} because in range
   • Additional namespaces are added after the current namespace via common.tplvalues.render

3. Preserved dashes before include to prevent line breaks when using nindent

Example of correct YAML structure

requiredDuringSchedulingIgnoredDuringExecution:
  - labelSelector:
      matchLabels:
        ...
    namespaces:
      - current-namespace
      - additional-namespace1
      - additional-namespace2
    topologyKey: ...

Testing

Changes were tested on Helm chart rendering with various namespace configurations.
