#18811
* Fixed bug where fleetd-chrome sent multiple read requests to Fleet
server at the same time.
* Improved console log output messages when Fleet server is down.
Add GitHub Actions for releasing fleetd-chrome beta and production. See
the included README updates for details.
This was tested with an `on: pull-request` trigger for the beta workflow
which is now removed for merging into the repo.
