Update the version number, npm is out of sync with repo

[kashyap-aditya]

The version number might need to be updated because the current version 1.1.3 that is installed from npm still has sequelize 5.22.x whereas the package.json in the repo here has been updated to 6.x.x.

https://www.npmjs.com/package/botbuilder-storage-postgres/v/1.1.3?activeTab=code

either the version number needs to be updated or the GitHub code needs to be synced with npm registry some other way
