Text "Set Password" instead of "Reset Password" on "/docs/labs/developer-track/lab05/walkthrough.adoc"

On "Add User to Realm" item 6, the text "Click on Reset Password." should be "Click on Set Password.". The first time the user set a password, the button text is "Set Password" (as the attached image) and after the password set confirmation, the text changes to "Reset Password".
