Upgrade tooling to fix broken build (#300)

- Have tox install current LTS release of nodejs
- Have tox install latest v2.x release of CDK CLI
- Update pip editable install to work with pip 25+

The last point addresses the following warning when running tox:

> DEPRECATION: Legacy editable install of hls_lambda_layer==0.0.0 from
> file:///Users/chuck/src/NASA-IMPACT/hls-orchestration/layers/hls_lambda_layer/python
> (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour
> change. A possible replacement is to add a pyproject.toml or enable
> --use-pep517, and use setuptools >= 64. If the resulting installation
> is not behaving as expected, try using --config-settings editable_mode=compat.
> Please consult the setuptools documentation for more information.
> Discussion can be found at pypa/pip#11457
