for #2543
BREAKING CHANGE: semantic-release is now ESM-only. since it is used through its own executable, the impact on consuming projects should be minimal
BREAKING CHANGE: references to plugin files in configs need to include the file extension because of executing in an ESM context
- Allow to run semantic-release (via API) from anywhere passing the current working directory.
- Allows to simplify the tests and to run them in parallel in both the core and plugins.
