Docs: Feedback for Updating Map Entries

Hi, I have some feedback about [this page](https://github.com/hazelcast/hz-docs/edit/main/docs/modules/data-structures/pages/updating-map-entries.adoc)

Specifically in this section: [Deleting individual map entries](https://docs.hazelcast.com/hazelcast/5.4/data-structures/updating-map-entries#deleting-individual-map-entries).
There doesn't seem to be a clear(K) method (at least in the Java and Go client)

Start with docs/modules/data-structures/pages/updating-map-entries.adoc and inspect the “Deleting individual map entries” section. Compare its documented methods with the Java and Go client APIs, then update the section so it accurately reflects the available operations.
