bot/modules/nostr: convert to TS

[webwarrior-ws]

Convert bot/modules/nostr to TypeScript.
Specified "lib" property in tsconfig.json because otherwise TypeScript compiler complains about usage of Promise.any in bot/modules/nostr/index.ts:

Property 'any' does not exist on type 'PromiseConstructor'. Do you need to change your target library? Try changing the lib compiler option to 'es2021' or later.

Hi @webwarrior-ws when I type /nostr have an Error

and when type /npub with a correct npub this the bot says:
⚠️ ERROR Not a valid NIP-19 (https://github.com/nostr-protocol/nips/blob/master/19.md) npub. Please check your input.

@Catrya take a look, I added a commit that should fix the error. Assuming NOSTR_SK env. var is hex-encoded. If not, tell me what format it is in.

Hi, @webwarrior-ws it keep getting the same 2 errors: with /nostr and /setnpub

Anyway, what do you think @grunch about removing the /setnpub part because in the end I think that was no longer working anyway (I'm not referring to the current error of not accepting npub, but to what it was intended to do, which was to notify the user through nostr if someone took their order, and I can't find the 20100 events that it should publish in the relays) Or maybe leave it and then evaluate whether to keep that feature and fix it?
