Reimplement markup language in Lezer or not

As for an actual request: Some sort of “Inspect Tokens” feature like VSCode has would be really handy for debugging the output of a grammar. Currently, you have either look at the raw tree through some sort of pretty printer or by just visual examination of the token colors to debug a grammar.

I shared a pretty printer for this purpose recently: What's the best to test and debug grammars? - #3 by grayen

It is far from perfect, but it has helped me a lot while developing my grammar.
