Your requirements describe Lua. Lua is designed to be emendable as well as work as a declarative configuration language.

Other options I’ve seen or used include Tcl, Python, and JavaScript.

All of these languages can be embedded to various degrees of work and tend to be fairly easy for non-programmers (who think they can program) to use.
