feat: set schema statically

[acao]

this allows users to set the language service schema using an SDL string or an introspection JSON result

also in this PR:

• move and correct the monaco.d.ts (still no proper definitions, api intellisense)
• make createData simpler
• update docs, fix a typo
• add npmignore lines for tsbuild output which adds a whole MB or more to our npm package

LGTM 🔥

@Nishchit14 it is not sadly, been churning on the triple slash directives for monaco since last weekend :(. still can't get the monaco API patterns working right

[acao]

can't seem to get the module extensions working again

[Nishchit14]

I see I like the spec by reading the README. But as I am a newbie for TS and Monaco I could not go into the implementation. But I am learning it and I wish soon I can help you. :)

this was accomplished in a better way in another upstream PR

[connorshea]

@acao sorry, could you explain what you mean by another upstream PR? I'm interested in this functionality and I'm not sure what you mean :)

[harshithpabbati]

@connorshea he means about this #1575 PR

[acao]

@connorshea my bad., a clearer thing to say is that this has been released in the latest version of [email protected] 🎉 . note that there is a breaking change in the API, please read the docs

docs are in the subpackage readme. enjoy! let me know if there are issues please
