feat: add PDB and probes, drop unspecified acl in sentinel helm

[Dariusch]

Description

This pull request includes several updates to the Redis Sentinel Helm chart, focusing on the removal of ACL-related configuration and the addition of Pod Disruption Budget (PDB) and probe configurations.

• Removal of ACL Configuration
  • Redis Sentinel does not support ACL
• Added PDB and probe configuration options (livenessProbe, readinessProbe) to charts/redis-sentinel/README.md.
• Added PDB and probe configuration blocks to charts/redis-sentinel/templates/redis-sentinel.yaml.
• Added PDB and probe configuration defaults to charts/redis-sentinel/values.yaml.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

Checklist

• Tests have been added/modified and all tests pass.
• Functionality/bugs have been confirmed to be unchanged or fixed.
• I have performed a self-review of my own code.
• Documentation has been updated or added where necessary.

Additional Context

The probe values were taken from the in-cluster rendered defaults for our RedisSentinel deployment.

In addition, I was wondering if there are any plans to support a PDB for redis-replication.
