docs: update compatibility matrix and standardize example images to latest

  - Simplify Image Compatibility section in README
    - Remove outdated version compatibility table (only updated to v0.19.x)
    - Emphasize using latest stable Redis versions for security fixes
    - Clarify that operator supports Redis >=6.x without strict version dependencies

  - Update all example manifests to use 'latest' image tags

  This change reduces maintenance burden and ensures examples always
  reference the latest stable versions with security patches.

  Fixes #1529

 ## Image Compatibility

+The operator supports Redis versions `>=6.x`. However, **it is strongly recommended to use the latest stable version** to ensure you have the latest security fixes and bug patches from upstream.
