Better crowdin command documentation.

[rickyvetter]

Currently in the translation documentation it's recommended that you add a line like: "crowdin-upload": "export CROWDIN_DOCUSAURUS_PROJECT_ID=$YOUR_CROWDIN_ID; export CROWDIN_DOCUSAURUS_API_KEY=$YOUR_CROWDIN_API_KEY; crowdin-cli --config ../crowdin.yaml upload sources --auto-update -b master", to your package.json. What is crowdin-cli? It doesn't work the the npm i crowdin-cli package, and the recommended crowdin cli uses the crowdin command. Is there a different package I should be looking at?

Hi, this is outdated.

One way to handle this is to set an environment variable in the crowdin.yaml config file. The cli will then pull keys from ENV. This also makes it easier for circle ci integration and hides the keys.

I'll add a line about installing the cli through brew or apt-get for ubuntu.

I have requested that Crowdin In add a public read-only method for downloading strings so that we don't need this complex step. In meantime, I'll update the docs to add instructions for installing crowdin.
