Add toggle for plaintext table editing in Live Preview mode

Made an account to add to this FR. The landing page for Obsidian says: “Obsidian is the private and flexible writing app that adapts to the way you think.”. There’s a lot of discontent with this forced feature migration, please allow the users that do not want the new table editor to opt out of it

This table behavior does not match the behavior of WYSIWYG editing with other content, such as YAML, source code blocks, markdown headers and other markdown formatting. If my cursor enters something with a rich view, I want to be editing the source code behind that view. Learning a new set of keybinds is not something I’m going to do here. I’m going to open my folders full of markdown in VSCode and resolve the pain point. Please rethink this.
