Remove legacy Java versions from dependency statement

That's not what the POM says. It requires Java 8.

[elharo]

which is why I removed the note saying that Java 5 is required

[aherbert]

I think this change is fine. The reference to Java 1.2 and 1.5 are no longer relevant and adding back a different Java version adds a maintenance burden syncing the required java version across various documentation.

Java 8 CI for Mac is borked:

Re MacOS, I think we have to switch the setup-java distribution to zulu. Or just drop the windows and mac os from the actions given the code does not use anything platform dependent. I'll push a change to master using zulu and see what happens.

[aherbert]

Switching to zulu has fixed the master build.

The simplest is to use macos-13.
The title here is "Assume everyone is on Java 5 or later" which is not the case, we need Java 8 or later.

[aherbert]

The title is just from the commit message. The code change is to remove statements that spread the dependency information across site documentation (which is evidently not maintained in sync).
