Replaced monaco-editor bundled dompurify with 3.2.4 version (#242522)

## Summary

`kbn-ui-shared-deps-src` embeds DOMPurify 3.0.5 instead of 3.2.4 because
Monaco Editor bundles its own DOMPurify 3.0.5. `@kbn/monaco` imports
from `monaco-editor`, which includes a bundled DOMPurify 3.0.5 at
`node_modules/monaco-editor/esm/vs/base/browser/dompurify/dompurify.js`

## How to test
Build and check that we have embedded DOMPurify 3.2.4
```grep -a "@license DOMPurify" kibana/target/build/src/platform/packages/private/kbn-ui-shared-deps-src/shared_built_assets/kbn-ui-shared-deps-src.js```
