Restructuring the Repo to make it clear the difference between classic autogpt and the autogpt platform:
* Move the "classic" projects `autogpt`, `forge`, `frontend`, and `benchmark` into a `classic` folder
* Also rename `autogpt` to `original_autogpt` for absolute clarity
* Rename `rnd/` to `autogpt_platform/`
* `rnd/autogpt_builder` -> `autogpt_platform/frontend`
* `rnd/autogpt_server` -> `autogpt_platform/backend`
* Adjust any paths accordingly
- Moved `autogpt` and `forge` to project root
- Removed `autogpts` directory
- Moved and renamed submodule `autogpts/autogpt/tests/vcr_cassettes` to `autogpt/tests/vcr_cassettes`
- When using CLI agents will be created in `agents` directory (instead of `autogpts`)
- Renamed relevant docs, code and config references from `autogpts/[forge|autogpt]` to `[forge|autogpt]` and from `*../../*` to `*../*`
- Updated `CODEOWNERS`, GitHub Actions and Docker `*.yml` configs
- Updated symbolic links in `docs`
