Add AST JSON files for new documentation and scripts

- Created JSON representation for `collect-diagnostics.sh` including nodes and edges for its structure.
- Added JSON for `ops-restarts.md` detailing various sections and their relationships.
- Introduced JSON for `server-down-oom-diagnosis.md` capturing its content and connections.
