config: disable Java analysis

Java analysis consumes significant memory resources, even when only the
Java SDK is analysed.

Java analysis populates autocomplete with a huge number of entries from
the Java language API, adding complexity when not using Java interop.

Set `:java nil` to disable LSP analysis of Java SDK and any other Java
libraries on the class path
