## Description
The current config breaks when mason is not installed (e.g. for Nix
users). This PR makes the mason-related functionality (which, as of now,
consists only of finding `lombok`) dependent on mason being installed.
As noted in the commit, this does make it impossible to use lombok
without mason, but I'm unaware of any other method of finding it (which
is why mason-registry was used in the first place, I assume)
Please note that I'm not very experienced with Lua and the code might be
not the most idiomatic one.

Currently, there are no Java configurations for nvim-dap upon enabling
the Java extras.
This requires debugging configurations to be setup manually afterwards.
(This is unlike many other language extras which do have nvim-dap
support "out of the box")
This pr creates an initial configuration for nvim-dap which lets it
attach to a debugging process on port 5005.
(such as a spring boot application) More can be added if there are any
experienced Java devs here.

## Description
Problem
In the default configuration `opts.test` is a boolean and the code tries
to access `opts.test.config_overrides` which results in an error.
Solution
Use control flow to return nil in the case of `opts.test` being boolean.
