[camdecoster]

Description

Update type generator to include trace-contributed layout attributes.

Closes #8018.

Changes

• Update generator script
• Update types
• Update docs

Testing

• Be on main
• Save the following in the project root:

  import type { Layout, PolarLayout } from './src/types/index';
  declare const l: Layout;
  declare const p: PolarLayout;
  l.barmode = 'relative'; l.barnorm = 'fraction'; l.bargap = 0.1;
  l.boxmode = 'group'; l.violinmode = 'overlay'; l.funnelmode = 'stack';
  l.waterfallmode = 'group'; l.scattermode = 'group'; l.hiddenlabels = ['a'];
  l.piecolorway = ['red']; l.sunburstcolorway = ['red']; l.treemapcolorway = ['red'];
  l.iciclecolorway = ['red']; l.funnelareacolorway = ['red']; l.extendpiecolors = true;
  p.barmode = 'overlay'; p.bargap = 0.3;
  l.polar2 = { barmode: 'stack' };
  // @ts-expect-error barpolar supports only stack/overlay
  p.barmode = 'relative';
  // @ts-expect-error enum still rejects bad values
  l.barmode = 'nonsense';
  // @ts-expect-error unknown keys still rejected
  l.notAReal = 1;

• Run the following command:

  npx tsc --noEmit --ignoreConfig --strict --skipLibCheck --moduleResolution bundler --module esnext --target es2020 ./temp.ts
  

• Note that the result is an error
• Switch to this branch
• Run the command again
• Note that no error occurs
