Update schema files

As the schema files are downloaded on first use, they may need to be updated from time to time, as more features are added in the configuration.
This is done by deleting the existing schema files in the following directory.

C:\Users\<YourUsernameHere>\.lemminx\cache\http\schemas.taskletfactory.com\MobileWMS
