Rewrote readme and develop files to include instructions closer to what I assume how it works.<br>
I have no idea how the docker setup works since at quick glance it uses some syntax I don't know and relies on hardcoded image references, which is not good for local development.

## Updates

- `README.md`:
   - added level 1 heading.
   - removed submodule-related logic since it looks like the repo doesn't use it because there is no `.gitmodules` file to declare them and `archiver` folder is empty.
   - removed `pre-commit` install logic since it has to be run only for development and only after creating a virtual environment.
   - added `--interactive` flag to all `cp` examples in order not to overwrite the file in case it exists already.
   - where applicable replaced short-form CLI options with long-form ones.
   - moved all inline comments outside of shell code blocks.
   - removed `virtualenv --upgrade-embed-wheels` because it doesn't in fact makes managing python versions easier.
- `docs/Develop.md` -> `docs/develop.md`:
  - basically the same as `README.md` changes but with more detailed instructions for development.
- `.vscode/extensions.json`:
  -  `"ms-python.vscode-pylance"` is included along with `"ms-python.python"` so no reason to rec separately.
  - `"ms-toolsai.jupyter"` is same as above.
  - `"rioj7.command-variable"` is not relevant anymore.
- `.vscode/settings.json`:
  - removed `"json,schemas"` settings because it doesn't look like json schemas are used anyway.
  - removed `python.linting.*` settings because they live in a separate extension now.
- `configs/workspace.code-workspace.example`:
  - removed `archiver` workspace
  - removed length-related settings since they don't make sense without some root config set up first.

## Deletions

- `archiver`<br>
   Is not used anymore.
- `.github/workflows/build.yml`<br>
  Has references to `OpenYiff` github org so I assume it's not relevant anymore.
- `.vscode/launch.json`<br>
   Not relevant anymore.
- `doc/Setup.md`<br>
   Outdated and the setup instructions are not big enough to warrant a separate file.
- `json-schema` <br>
   The repo doesn't seem to use json schema so these files are completely irrelevant.
