Due to the build/publish single-file output rule, @lexical/code-shiki includes every Shiki import and causes the bundle to grow by 8-9 megabytes.

Lexical version: v0.44.0

Steps To Reproduce

1. Install @lexical/code-shiki
2. import @lexical/code-shiki somewhere

The current behavior

Shiki is wholly bundled in the main bundle (or Lexical's chunk if Lexical is lazy-loaded)

The expected behavior

Shiki is not bundled with the app;
CodeNode should source its code language and theme from Shiki on-demand (default Shiki behavior)

Impact of fix

Apps that use @lexical/code-shiki would be 8-9 megabytes lighter
