[Bug] v2.20.0 sanitises by default

The output of v2.20.0 has html tags removed by default. This does not happen with 2.19.3.

Steps to reproduce:

1. Use example.html and set script for editor to <script src="https://cdn.jsdelivr.net/npm/@editorjs/editorjs@latest"></script>

2. Format some of text using basic HTML:

3. click 'editor.save()' button to generate JSON:

4. revert script for editor to <script src="https://cdn.jsdelivr.net/npm/@editorjs/editorjs@2.19.3"></script>

5. Format some of text using basic HTML:

6. click 'editor.save()' button to generate JSON:
