[BUG]: Layout type is missing all trace-contributed layout attributes in v4.0.0 (barmode, boxmode, scattermode, …) #8018

Description

Updating to plotly.js 4.0.0 broke typechecking in my project since the generated Layout type omits every layout attribute contributed by a trace module, i.e., barmode (there are 30 of these). These are all valid and work at runtime, but they don't exist in the type Layout, failing the typecheck and thereby my pre-commit.

Steps to reproduce

import type { Layout } from "plotly.js";

declare const layout: Layout;

layout.barmode = "overlay";
layout.bargap = 0.1;
layout.boxmode = "group";
layout.violinmode = "overlay";
layout.scattermode = "group";
layout.piecolorway = ["red", "green"];

All six layout references should give an error.

Notes

Plotly.validate (plotly.js 4.0.0) treats these as valid layout keys:

{ barmode: "overlay" }  -> []
{ barmode: "nonsense" } -> ["value: In layout, key barmode is set to an invalid value (nonsense)"]
{ notARealAttr: 1 }     -> ["schema: In layout, key notARealAttr is not part of the schema"]

Note the differing codes: barmode gets a value error (key recognised, value checked
against the enum), while an unknown key gets a schema error. So the runtime considers
layout.barmode part of the schema even though the type says it does not exist. This leads me to believe that this is an unwanted change / a bug.
