Hi,
I would like to know how to specify dmd or ldc compiler and
version in a json dub file.
Thanks in advance.
You can't [1]. You can specify the compiler to use only on the
dub command line via `--compiler=`.

How do you distribute packages with specific compiler
dependencies? I guess I could write it in the readme.
If your code depends on capabilities of a specific D compiler, I
wouldn't depend on build tools for that, I'd make it clear in the
source code via conditional compilation [1]:
---
version (DigitalMars)
{
}
else version (LDC)
{
}
else
{
static assert (0, "Unsupported D compiler");
}
---
There's no equivalent for the frontend version, though AFAIK.
If it's not your code that needs something compiler specific, but
you just want to control which is used, don't use dub as a build
tool, use another (cmake, meson, write your own compilation
"script" in D), and set it's invocation as a prebuildcommand in
the dub package file (make sure dub's source file list is empty).
