Create ADO pipeline to scan and generate English jsons containing localization data

[apoorvdeshmukh]

We have a localization pipeline that generates the artifacts for localization when triggered. However, this pipeline would be triggered weekly and needs the updated English JSON file if there is any new content. Creating this issue to track the final pieces of work that maybe needed as part of onboarding go-sqlcmd with localization team.

### Tasks
- [x] Add  Localization.md that contains instruction on generating JSON files after a new content has been added for localization
- [ ] Automate above via a weekly pipeline job

We will be using build.cmd to update the JSON files received from localization pipeline from locale directory.
