[maven-release-plugin] prepare for next development iteration

- remove references to 32 bit macos/darwin
- normalize Redis server file names
- update `build-server-binaries.sh` to statically link openssl on macOS
- correctly detect macOS and Unix architectures

+This repository is a fork of https://github.com/ozimov/embedded-redis, which is in turn a fork of https://github.com/kstyrc/embedded-redis. We've updated the embedded Redis binaries to version 7.0.15 so we can write tests that use recent Redis features without imposing dependencies that are not well-encapsulated by a single Maven/Gradle build.

 Redis version
 ==============
 
-When not provided with the desired redis executable, RedisServer runs os-dependent executable enclosed in jar. Currently is uses:
-- Redis 2.8.19 in case of Linux/Unix
-- Redis 2.8.19 in case of OSX
-- Redis 2.8.19 in case of Windows: https://github.com/MSOpenTech/redis/releases/tag/win-2.8.19
+By default, RedisServer runs an OS-specific executable enclosed in in the `embedded-redis` jar. The jar includes:
 
-However, you should provide RedisServer with redis executable if you need specific version.
+- Redis 7.0.15 for Linux/Unix (i386, x86_64 and arm64)
+- Redis 7.0.15 for macOS (x86_64 and arm64e AKA Apple Silicon)
+
+The enclosed binaries are built from source from the [`7.0.15` tag](https://github.com/redis/redis/releases/tag/7.0.15) in the official Redis repository. The Linux and Darwin/macOS binaries are statically-linked amd64 and x86 executables built using the [build-server-binaries.sh](src/main/docker/build-server-binaries.sh) script included in this repository at `/src/main/docker`.  Windows binaries are not included because Windows is not officially supported by Redis.
+
+Note: the `build-server-binaries.sh` script attempts to build all of the above noted OS and architectures, which means that it expects the local Docker daemon to support all of them.  Docker Desktop on macOS and Windows supports multi-arch builds out of the box; Docker on Linux may require [additional configuration](https://docs.docker.com/buildx/working-with-buildx/).
+
+Callers may provide a path to a specific `redis-server` executable if needed.

To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
