Create Langeuage Server to edit tid in VSCode, or provide highlight in codemirror inside wiki

[linonetwo]

1. Use https://langium.org/ to create a Language server
2. Write a server side plugin to run this server, provide a new server router that provides LSP
3. Codemirror or other editor can use this as syntax highlighter
4. Release this as a new VSCode plugin

Hi @linonetwo it would be great to have a TiddlyWiki language server. I think that on the TW side we still need to update some parse rules to set start/end ranges in their output.
