feat(nodes): add version to node schemas

The `@invocation` decorator is extended with an optional `version` arg. On execution of the decorator, the version string is parsed using the `semver` package (this was an indirect dependency and has been added to `pyproject.toml`).

All built-in nodes are set with `version="1.0.0"`.

The version is added to the OpenAPI Schema for consumption by the client.
