@codemirror/language-data creates 100+ unnecessary chunks when code plugins are not used

[greg-betterreports]

I've noticed that MDXEditor includes @codemirror/language-data as a dependency, which causes bundlers to generate 100+ lazy-loaded language chunks even when codeBlockPlugin and codeMirrorPlugin are not used. We are not using any of these feature as we just want basic formattting.

Impact:

• Before MDXEditor: 14 lazy chunks
• After MDXEditor: 150+ lazy chunks (python, sql, css, ruby, perl, etc.)
• Initial bundle only increased by ~10 kB, but deployment now has 136 extra files

Reproduction
My imports (no code plugins):

import {
    MDXEditor,
    headingsPlugin,
    toolbarPlugin,
    BlockTypeSelect,
} from '@mdxeditor/editor';

Build result:

chunk-CWTJBLNK.js     | python    |   6.53 kB
chunk-SMLDLULW.js     | sql       |  37.15 kB
chunk-5K5AGJRX.js     | css       |  27.25 kB
... (100+ more language files)

Would there be a way to not include those chunks if we don't use the code plugin ?

Thank you !
