"Open File for Editing Button" is broken

[pattch]

In the Cloud Shell tutorial, the button for "Open File For Editing" seems to be intending to open the Tutorial in the editor, but the filePath is not correct.

Instead of cloud-shell-tutorials/tutorial.md it should rightly be cloudshell_open/cloud-shell-tutorials/tutorial.md

So overall, the tutorial should be updated to the following:

To include a link to <walkthrough-editor-open-file filePath="cloudshell_open/cloud-shell-tutorials/tutorial.md">open a file for editing</walkthrough-editor-open-file>, use:

With the following code snippet:

<walkthrough-editor-open-file
    filePath="cloudshell_open/cloud-shell-tutorials/tutorial.md">
    open a file for editing
</walkthrough-editor-open-file>
