Add amble_engine and amble_script to data.toml (#632)

* Add amble_engine and amble_script to data.toml

Added two separate entries for my Amble game / engine / DSL / compiler / linter, since it's split into two different crates:
- amble_engine: the actual game engine / content loader and the playable demo game
- amble_script: the DSL / compiler / linter -- not technically necessary to make games in amble_engine (content can be written directly in TOML)  but makes it far easier to create complex scripts / interactions / puzzle chains / etc.

* Update data.toml
