refactor(payload): rename apollo to ares and update documentation

This commit renames the Apollo payload type to Ares, moving all associated files and updating documentation accordingly. The change includes:
- Renaming directories from `apollo` to `ares`
- Updating documentation image references
- Maintaining the same code functionality while changing the payload name
- Adding new Ares-specific documentation files
- Removing old Apollo documentation files

The rename is done to reflect the new payload name while preserving all existing functionality.
