build: removed generation of docs index

- Remove the `gen:docs` step from the Docker build process and the developer documentation.
- Update documentation in `docs-index.ts` to reflect that the index is now injected via environment variable instead of a generated file.
- Update error messaging to point to binary or bundle rebuilds rather than the deprecated generation script.
