Add post-installation notes

[databyjp]

Add NOTES.txt and version status tracking

This PR introduces two new files:

• templates/NOTES.txt - Provides version information and support status on Helm install
• files/weaviate-issues.yaml - Contains version metadata for tracking support status

The NOTES.txt file displays conditional messages, containing:

• The installed version
• Latest available version
• Any later patch versions
• Support status information and
• Relevant warnings for known issues that affect the installed version.

The relevant latest patch version information, support status & warnings are pulled from files/weaviate-issues.yaml. This is designed to be centralised source of truth for easy maintenance.

---

Example: create this yaml file with a custom config:

# Custom configuration for Weaviate

# Specify a different Weaviate version to trigger notes
image:
  tag: 1.30.0

# Set resources
resources:
  requests:
    cpu: '500m'
    memory: '500Mi'
  limits:
    cpu: '1000m'
    memory: '1Gi'

# Use ClusterIP instead of LoadBalancer for testing
service:
  type: ClusterIP

# Set a smaller storage size for testing
storage:
  size: 10Gi

Then perform dry run installation e.g.:

helm install --dry-run --debug my-weaviate weaviate/ -f my-values.yaml
