markdown: Fix rendering of inline HTML <code> tags (#43513)

Added support for rendering HTML `<code> `tags inside Markdown content.
Previously, these tags were ignored by the renderer and displayed as raw
text (inside LSP hover documentation).

Closes: #43166 

Release Notes:
- Fixed styling of `<code>` HTML tags in Markdown popovers.
