following up #420

I ended up there while bisecting repository → repositoryBase 's silent (and partialy a breaking) change. I believe this PR removed support of setting repository in the configuration file, which makes tldr fallback to default assets instead of the specified one. To handle this:

• Update documentation according to the code (to supply a base url and construct the actual download inside tldr) and note it's a breaking change
• Add a condition to allow all-language download if repository was specified (this makes it backwards compatible)

I think one of the two (prefferably both) of the above measures should be taken. (I think the second one should be implemented with a deprecation warning of some form as it's inefficient for both the client and the server)(if we're going to implement it)

Affected codes between prior to #420 and the current main branch (7ad3c5a..c58c92c):

• config.json:
  

  tldr-node-client/config.json

  Line 3 in 7ad3c5a

  "repository": "https://tldr.sh/assets/tldr.zip",

  
  

  tldr-node-client/config.json

  Line 3 in c58c92c

  "repositoryBase": "https://tldr.sh/assets/tldr-pages",

• lib/cache.js
  

  tldr-node-client/lib/cache.js

  Lines 53 to 56 in 7ad3c5a

  	.then(() => {
  	// Download and extract cache data to temporary folder
  	return remote.download(tempFolder);
  	})

  
  

  tldr-node-client/lib/cache.js

  Lines 51 to 56 in c58c92c

  	.then(() => {
  	// Download and extract cache data to temporary folder
  	return Promise.allSettled(this.config.languages.map((lang) => {
  	return remote.download(tempFolder, lang);
  	}));
  	})

• lib/remote.js
  

  tldr-node-client/lib/remote.js

  Lines 8 to 9 in 7ad3c5a

  	exports.download = (path) => {
  	const url = config.get().repository;

  
  

  tldr-node-client/lib/remote.js

  Lines 10 to 15 in c58c92c

  	exports.download = (loc, lang) => {
  	// If the lang is english then keep the url simple, otherwise add language.
  	const suffix = (lang === 'en' ? '' : '.' + lang);
  	const url = config.get().repositoryBase + suffix + '.zip';
  	const folderName = path.join(loc, 'pages' + suffix);
  	const REQUEST_TIMEOUT = 10000;

I don't have time currently to make a PR on my own now, so I would appreciate if someone could handle this. However if this remains for a month or two, maybe I can put my hands on it.
