fix: add Apache-2.0 license metadata to all packages (#528)

Several packages were missing explicit license fields or had incorrect
license metadata:

- python/handlebarrz: add license = "Apache-2.0" and License classifier
- js: fix license from ISC (npm default) to Apache-2.0
- root package.json: add license field
- packages/treesitter: fix license from MIT to Apache-2.0
- python/dotpromptz: add License classifier
- python/dotpromptz/tests/smoke: add License classifier
- python/handlebarrz/smoke_tests: add license field
- dart/dotprompt: add license field
- dart/handlebarrz: add license field

All packages in this repo are Apache-2.0 licensed. The ISC license on
the JS package and MIT on treesitter were leftover defaults from npm
init and the tree-sitter template respectively.
