[Taskcluster] pin Chrome Dev to 78.0.3904.17 (#19360)
The URL pattern can be discovered by installing Chrome Dev and then running
`apt-get download --print-uris google-chrome-unstable`. These URLs are probably
not stable forever, but it was confirmed that the version used for a Taskcluster
run back in Feburary 28 is still available:
https://dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-unstable/google-chrome-unstable_74.0.3717.0-1_amd64.deb
The version pinned here is from the last successful Taskcluster run before
Chrome Dev 79: https://tools.taskcluster.net/groups/fwiwJe9RSQ22S1HaAZaE-g
Mitigation (not fix) for https://github.com/web-platform-tests/wpt/issues/19297.
