On a M3 Max macbook pro with 14 cores,
Before:
```
=> [25/44] RUN /tmp/install-imagemagick 150.6s
=> [27/44] RUN /tmp/install-jemalloc 54.9s
=> [31/44] RUN /tmp/install-redis 42.9s
```
After:
```
=> [25/44] RUN /tmp/install-imagemagick 44.4s
=> [27/44] RUN /tmp/install-jemalloc 13.7s
=> [31/44] RUN /tmp/install-redis 11.7s
```
This unlocks using the new I/O Threads feature of Redis 6.X.
In order to support it the redis template file now accepts a parameter
allowing an operator to enable it and pick how many threads.
By default sets threads to 1, which disables the feature and acts like
redis 5.
Including minor upgrades for redis,ruby,image magick, libpng
One notable thing here is that I removed the SHA check from redis
I am not against checking SHA but we need to explode if it fails and do
something far more consistent across our various downloads
