Markdown does not function fully anymore

[Catherine358]

Describe the bug
When user tries to use markdown in volto text editor, for example to write "# Some title", "#" symbol disappears, but text stays to be usual text (p element). However in toolbar buttons text is marked as being "Title" (h2 element). Same behavior can be seen for Subtitle and block quote. Bold and italic texts do not work at all. But unordered and ordered lists do work fine.

To Reproduce
Steps to reproduce the behavior:

1. Go to Edit Mode.
2. Add text field.
3. Write "# Text"
4. Save

Expected behavior
Markdown works. When user types "# Title", he sees h2 element without "#" symbol instead of usual text. When user types "## Subtitle", he sees h3 element without "##" symbol instead of usual text. When user types "> some text", he sees blockquote element without ">" symbol instead of usual text. When user types "Text", he sees bold text without "**" symbol. When user types "Text", he sees italic text without "*" symbol.

@Catherine358 #5495 resolved issue #5452, was applied to the main branch of Volto, and released in https://github.com/plone/volto/releases/tag/plone-slate-18.0.0-alpha.14.

It was not backported to Volto 17.

We'd accept a pull request that backports the fix to Volto 17. Would you like to contribute?
