Issue found on page 'Window Functions'

[vlulla]

Duckdb, in v1.2.0, got "Groups" framing for window functions. The documentation describes this framing clause but the railroad syntax diagram, at the top of the page, is missing this groups branch. This branch is also missing on the window clause page of the query syntax.
