Remove git dependencies from package.json

Is your feature request related to a problem? Please describe.
Here we install a few git repositories during the npm install process -- https://github.com/plasma-group/plasma-chain-operator/blob/master/package.json#L56-L58 . This isn't ideal considering there's no version tracking.

Describe the solution you'd like
Replace this with direct references to the npm package with version number.

I can take care of it.
but it looks like plasma-explorer is not on npm.
Should I submit a pull request with only plasma-contract and plasma-utils updated ?

Amazing! Yes actually you can remove plasma-explorer generally. It's not being used at the moment & I just forgot to take it out.
