[georgebisbas]

The examples/workers/l3/README.md table listed seven directories while the tree has ten. Add allgather_distributed and reduce_scatter_distributed with the same New concept style as the existing rows.

The L3 examples README table is extended with two new rows documenting distributed communication examples: allgather_distributed/ and reduce_scatter_distributed/. Each entry describes the orchestration-time domain allocation and per-rank communication workflow for those patterns.

A rabbit hops through examples so fine,
Two new dancers join the communication line,
Allgather and reduce-scatter take their bow,
Distributed patterns documented now! 🐰✨
