Subject: [PATCH] Add GQL (Graph Query Language) concept page

Adds concepts/graph-query-language.scroll for ISO/IEC 39075:2024 GQL,
the first new ISO database query language standard since SQL in 1987.
Named graph-query-language since gql.scroll is already taken by a 1980
Birkbeck College language. Includes description, keywords, language
features, influenced-by links (sql, cypher, gsql, pgql, sparql),
ANTLR grammar reference, and Wikipedia metadata.

+description GQL (Graph Query Language) is a declarative, standardized query language for property graphs, published as ISO/IEC 39075:2024 on April 12, 2024. It is the first new ISO database query language standard since SQL was standardized in 1987. GQL queries property graphs by matching ASCII-art style node and edge patterns and supports both read and write operations on graph data.

+ summary GQL (Graph Query Language) is a standardized query language for property graphs first described in ISO/IEC 39075, released in April 2024 by ISO/IEC. GQL is a declarative language designed to query and update property graph databases, playing a similar role to SQL for relational databases. Property graphs store data as nodes (entities) and edges (relationships), each optionally having labels and properties. GQL was developed by ISO/IEC JTC 1 SC 32 WG3 — the same standards body responsible for SQL — and synthesizes ideas from industry-proven graph query languages including openCypher (Neo4j), GSQL (TigerGraph), PGQL (Oracle), and G-CORE. GQL is complemented by SQL/PGQ (ISO/IEC 9075-16:2023), which adds read-only property graph query support inside SQL SELECT statements. The standard spans 628 pages and was developed over five years (2019–2024), involving 38 meetings and contributions from organizations including Google, IBM, Intel, Neo4j, Oracle, and TigerGraph. Notable implementations include Google Cloud Spanner, Google BigQuery, and Microsoft Fabric. GQL is the first new ISO database query language standard since SQL in 1987.
