Fix readme

The json example was wrong (xliffmerge instead of xliffmergeOptions, and missing surrounding `{` `}`).
I also removed the comments that made your code crash (because there is no comments in json).
I added the detail of the commands below.

 ### Generate (untranslated) language files, if not already there
 When you run `xliffmerge`, it will read the master xliff file **messages.xlf**.
 This is the file generated by the Angular extraction tool `ng-xi18n`.
