CLI packaging cleanup (#682)

This is a continuation of the changes in
https://github.com/ente-io/ente/pull/681.

- git rm cli/config.yaml (this file was gitignored but it seems to be
present in the tree too)
- Remove goreleaser config since we're not using it anymore

I'm not sure if there is something in the goreleaser config that we also
need to pass to the the new action we're using to build the binaries
now, so please take a quick scan to see if something reminds you. If
needed, we should be able to set the corresponding build flag in the
[new release action](https://github.com/wangyoucao577/go-release-action)
too.
