It appears that prismjs gets included as a (very large) dependency of @lexical/markdown, swelling the bundle size.

Steps To Reproduce

See https://bundlephobia.com/package/@lexical/markdown@0.12.5 and that prismjs swells the bundle size

The current behavior

Prismjs is included in the bundle

The expected behavior

Prismjs is not included, and the bundle size is <100kb
