TypeScript compiler can't found declaration

[ikokostya]

• node version - v8.6.0
• celebrate version - 5.0.1
• joi version (via npm ls --depth=0 | grep joi) -

Explain the problem here

Now TypeScript declaration https://github.com/continuationlabs/celebrate/blob/master/lib/index.d.ts is presented in npm package, but can't be found by TypeScript compiler:

$ ls node_modules/celebrate/lib/index.d.ts 
node_modules/celebrate/lib/index.d.ts
$ ./node_modules/.bin/tsc 

t.ts(1,28): error TS7016: Could not find a declaration file for module 'celebrate'. '/home/kostya/tmp/ts-test/node_modules/celebrate/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/celebrate` if it exists or add a new declaration (.d.ts) file containing `declare module 'celebrate';`

1 import * as celebrate from 'celebrate';
                             ~~~~~~~~~~~

For fix this need to add property types to package.json of Celebrate package:

{
+ "types": "./lib/index.d.ts"
}
