Subject: [PATCH] fix(dogfood): chrome desktop icons with compatibility flags
 (#23209)

Our dogfood image already included chrome. Since we run dogfood
workspaces in Docker, chrome requires some compatibility flags to run
properly. If you launch chrome without them, some webpages crash and
fail to load.

The newest release of https://github.com/coder/portabledesktop added an
icon dock. This PR edits the chrome `.desktop` files so when you open
chrome from the dock it runs with the correct flags.
