Broken Dock ProgressBar

[MattKiazyk]

Describe the bug

When installing 15.3 this morning, the progress bar got stuck and didn't go away until I closed Xcodes.

With all the changes in the last few months, I probably broke this.

See previous PR: https://github.com/XcodesOrg/XcodesApp/pull/423

To Reproduce Try installing a new Xcode version and watch the progress bar on the dock

Expected behavior Progressbar should clean itself up after xcodes install.
