Greptile Summary

This PR fixes 24 pyang RFC 8407 compliance errors in yang/frr-bgp-common-structure.yang by adding required description substatements to grouping, container, choice, and list nodes, and a reference substatement to the revision block.

• All 24 errors listed in the PR description are addressed; no pyang-required substatements appear to have been missed.
• The reference "FRRouting"; value in the revision block is consistent with the pattern already used across 12 other FRR YANG modules.

Confidence Score: 5/5

Safe to merge — all changes are purely documentary metadata with no impact on runtime behavior or data model semantics.

Every change is a description or reference string added to YANG schema nodes. No leaf types, constraints, keys, or default values are touched, so existing implementations and generated code are unaffected.

No files require special attention.

Important Files Changed
