feat: typescript, tsx, jsx support for LSP server using babel

[acao]

• introduces typescript, tsx and jsx support via babel parser plugins
• feat: add support for more languages, starting with ReasonML #1263 by @zth is an alternative to solving this problem which also supports reasonml, and potentially other a non-ast branch by @zth using regular expressions should be reconsidered.
  -tests for typecript and tsx added
• getQueryAndRange changed to parseDocument, and made override-able as parse by startServer.

Does this do the same job as https://github.com/Quramy/ts-graphql-plugin?
If yes, are there any usage docs that I can refer to? 🤔

[acao]

yes! the only difference now is that it will handle ts/tsx files when you open them. still need to get vscode workspaces configured correctly to read all the embedded graphql up front

[acao]

to add, the typescript language plugin is still valuable for a lot of cases. this just replaces the need for it in the server

[zth]

This looks good to me! This will allow people who want to support other languages than the mainstream ones (like ReasonML for me) to do that through replacing parseDocuments. 👍

@zth last commit here fixes that bug i saw in discord, otherwise looks like everything is working fine! I've had some issues with setting up our example extension, but i think i understand what I'm missing after working with yours and @divyenduz 's more carefully.

note: I was not able to configure your graphql + reasonml extension to work with .ts or .tsx files to test this capability end to end, despite changing the clientOptions.documentSelector to follow the direction of others like vscode-graphql, but I can confirm this branch works great with both extensions.
