Pull request overview
Adds a new documentation blog post announcing Java Operator SDK v5.4.0, highlighting key features and migration notes for users following the project’s release cadence.

- Documents additional improvements and migration notes (shutdown hook deprecation, owner reference mapper changes, dependency snippet, comparison link).
| ### Shard Selector Support | ||
|
|
||
| Large clusters sometimes need the same operator to run as multiple replicas, each responsible for a | ||
| subset ("shard") of the resources. From 5.4.0 you can configure a **shard selector** — a second, |
| (e.g. `.../v1`) still resolve correctly after the served/storage version changes (e.g. to `.../v2`). | ||
| - **`GenericRetry#setMaxInterval(Duration)`**: a `Duration`-based overload alongside the existing | ||
| millis-based one, e.g. `new GenericRetry().setMaxInterval(Duration.ofMinutes(5))`. | ||
| - **Fabric8 client upgraded to 7.8.0**, which enables shard selectors and the re-list callback above. |
