Type error when configuring colors plugin.

[jaybeeuu]

Expected behavior

Following the examples in the docs, and when using a typescript project, the colors plugin can be configured, without type errors.

Current behavior

The colors plugin is not included in PluginOptionsByType. In typescript project trying to follow the examples in the docs leads to a type error.

Reproducible sample

Possible solution

One fix is really easy (and i have a branch ready to go if you want it...) which is to add the type into PluginOptionsByType

// /src/types/index.d.ts:2795

 export interface PluginOptionsByType<TType extends ChartType> {
+  colors: ColorsPluginOptions;
   decimation: DecimationOptions;
   filler: FillerOptions;
   legend: LegendOptions<TType>;
   subtitle: TitleOptions;
   title: TitleOptions;
   tooltip: TooltipOptions<TType>;
}

I wonder if it's been omitted on purpose though? Looking at the other plugins in there they are not ones you need to call register for (i.e. they appear to be "preregistered plugins"). That's quite reasonable since adding it into PluginOptionsByType makes it appear from the types to be available all the time, but you have to register it before you can use it. But in that case, it feels like there is an expectation that some declaration merging has to happen (as with the plugins that live in other packages) - doing that as a user feels a bit awkward.

So I wonder if the solution might be to expose the Colors plugin on an import path rather than on the root e.g. import { Colors } from 'chart.js/colors'; you would be able to add the declaration merge in a .d.ts on that path and give the users a better experience, and retain a similar behaviour to other plugins.

That would be a good fix
