Allow markdownShortcutsPlugin to insert nodes on newline without pressing SPACE (or document how to)

[0x0f0f0f]

I've found this discussion, but I found no later development.

#290 (comment)

It could be a simple flag: markdownShortcutsPlugin({insertNodesOnEnter: true}).

I tried implementing it myself by copying the plugin, but with no success, as I don't know why lexical is not picking the regexp up correctly for markdown transformers when pressing Enter, but still requires a space to be inserted.

An example can be seen in #714 when inserting a thematic break with ---.

(PS. I'd be glad to keep in touch. Feel free to send me an email!)

To be honest, I have no idea how to do that either. That part of the markdown shortcuts implementation is quite convoluted. If you want to help, you can search or ask for direction in Lexical's discord. The team does their best to keep things organized, yet I often struggle to find information in there.
