Update slim distribution documentation to remove Maven references [v/5.5] (#1707)

Backport of #1706

The documentation suggests there's a `slim` variant of `ZIP/TAR
Binaries` _and_ `Java` (effectively Maven) distributions.

This is _technically_ correct - [the `hazelcast-distribution` Maven
artifact offers both `slim` and regular `zip`
resources](https://repo1.maven.org/maven2/com/hazelcast/hazelcast-distribution/5.3.6).
However, further documentation about Maven exclusively talks about the
`hazelcast` artefact that doesn't offer this.

Rather than try to explain this nuance, I think it's easier to simply
drop references to `slim` + `Java` distributions.

I also think that as a concept, downloading a binary distribution
(rather than a dependency) is an atypical usecase of Maven, and that
following the _existing_ instructions might lead to confusion:
- Hazelcast offers a variety of download options, such as `slim`
- > [The slim distribution allows you to save memory by excluding
Management
Center](https://docs.hazelcast.com/hazelcast/latest/getting-started/editions#slim-distribution)
- You can download Hazelcast via Maven
- Logical next step - if you want to get started with Hazelcast, you try
to look for a `slim` `distribution` but really all you want is a
dependency

We can also simplify explaining how to obtain a `slim` variant - as both
the binary download (via website) and Docker (via Dockerhub) show the
variants and their names in their respective UI's anyway.
