Online builder file fails to output ARIA descriptions of charts

Hi there,

Thanks for all your hard work on ECharts and the great documentation for it.

## Issue description

When using the online builder to generate a leaner bundle containing only the features I am using, I noticed that switching to this bundle from the full uncompressed bundle broke the ARIA description.

I wondered if this was related to the features I had removed, so for experiment's sake I tried building an Echarts file with every chart, coordinate system, and component, which I would expect to be functionally identical to the full, uncompressed [echarts.js](https://github.com/apache/echarts/blob/5.6.0/dist/echarts.js) distribution, but this still didn't generate ARIA descriptions, and the bundle generated file was about ~300KB smaller than the full distribution.

## Reproduction

I have created a minimal test case showing this behaviour in action.
[Here](https://jegtnes.github.io/echarts-aria-bundle-reproduction/failure.html) is an HTML document rendering a chart with the builder bundle, not outputting an aria-label.
[Here](https://jegtnes.github.io/echarts-aria-bundle-reproduction/success.html) is an HTML document rendering a chart with the full bundle, successfully outputting an aria-label.

## Expected outcome
Generating an Echarts file from the online builder that includes the functionality to successfully output an aria-label from a chart.

## Actual outcome
Generating an Echarts file from the online builder does not include the functionality to successfully output an aria-label from a chart.

Let me know if you need any more information or if I can help to address this issue in any way. Many thanks!

Start with the linked failure.html and success.html reproductions, then compare the online builder output with the full dist/echarts.js bundle mentioned in the report. Trace how the builder includes the ARIA functionality and verify that a generated bundle produces the expected chart aria-label without requiring the full bundle.
