[Bug] Published npm package missing src/ files referenced by source maps, causing build warnings

[willresen]

Expected behaviour

The @highcharts/react npm package should either:

include the src/ directory referenced by its .js.map files, or
omit source map files from the published package if sources are not shipped

Actual behaviour

Every .js.map file in the published package (e.g. Highcharts.js.map, options/YAxis.js.map, options/index.js.map) references source files under a src/ directory (e.g. src/Highcharts.tsx, src/options/YAxis.tsx) that are not present in the published package. This causes source-map-loader to emit warnings for every file during webpack builds:

WARNING in ../../node_modules/@highcharts/react/options/YAxis.js Module Warning (from source-map-loader): Failed to parse source map from '...\node_modules\@highcharts\react\src\options\YAxis.tsx' file: Error: ENOENT: no such file or directory

Live demo with steps to reproduce

1. npm install @highcharts/react
2. Import and use any component from @highcharts/react in a webpack-based project (e.g. Create React App / CRACO)
3. Run the development build
4. Observe source-map-loader warnings for every file in the package

Hello willresen, thanks for sharing this!

I can clearly see this is an issue we will investigate internally. Since most of the bundled files remain quite readable, I think it would be optimal (considering bundle size) to at least include the source maps alongside the .tsx source files for the main, larger files.
