Upload source maps to sentry (#810)

* Pretend to upload source maps to sentry

* Build release not in docker so we can upload source maps sensibly

and also upload the release as a plain tarball while we're at it

* fix yaml

* Try specifying version this way

* test rebuild

* pass secrets through

* Too many sentries

* It's almost 2023 and we're still having BSD vs GNU tar issues

* Maybe get sensible tag name & release identifier

* Wrong plugin, and also try the 'release' option which might the right thing

* Try a different github action

see if github likes that any better

* add contents write permission

and switch to the asset upload plugin that had the helpful doc

* actually put release name in tarball path

* copy docker config to right path

* Prettify vite config

* Only activate sentry plugin if we have secrets

* Use env var for tag name

* Also spelling env correctly would likely help

* Fix variable syntax

* Put env var in correct place

One day maybe I will not find yaml syntax confusing
