Verify that autoupdate works

[dclear]

What happened (or feature request):

Autoupdate doesn't appear to be working.

What you expected to happen:

App updates are autodetected.

Ideally, via one of these:

• [ ] About DDEV UI gives the user feedback and instruction to update

• [ ] Or, on load during checks for DDEV Local and Docker, we also detect an old version of DDEV UI and prompt the user to update

How to reproduce this:

1. Remove any existing versions of DDEV UI app from machine
2. Download alpha from release page: https://github.com/drud/ddev-ui/releases/tag/v0.4.1-alpha
3. Open and confirm version
4. Close window, quit app.
5. Reopen and check version

===========================

• [x] Verify that the app auto-updates from version 0.4.0 to 0.4.1-alpha

So I just cut the internal alpha release - https://github.com/drud/ddev-ui/releases/tag/v0.4.0-alpha.0 and I'm not getting prompted to update :(

I'm going to dive a little deeper on this. We might need to use electron-updater. I'm going to spend under an hour seeing if I can get this dialed in as I'm pushing other updates. Would be very nice to have in place prior to release.

I have verified that this will work in insolation once the repo is public. PR #121

@alkymst : I am reopening this issue. I will put the testing steps I am using in the header.
