#3759 -- Needed to incorporate these changes into SSHWalletWidget
Detailed description of the pull request / Additional comments
WidgetViewModel's new MergeJsonData() function (#3759) has a parsing method that expects JSON string objects. While connecting via SSH, one of the strings passed into MergeJsonData() didn't have a key/value pair, which caused Dev Home to crash. Now, if the JSON parsing fails, the string parameter is wrapped as a JSON string object where the original string is set as the value of "data". This error case only occurs on the "Connect" action, so SSHWalletWidget has been updated to get the host from "data"'s value and use it in the SSH command.
The parameters for the merge method come from the AdaptiveCard, so preventing the parsing issue would require a more time-intensive refactoring.
Validation steps performed
Verified locally by clicking on a dummy host name. I get the same CMD error as entering "ssh {dummy_host}" in the CMD prompt.
