This is by no means a signal that we offer any additional guarantees with our software. This warning seems somewhat pointless given that:
1. Our open source license clearly states that we offer no warranties with this software.
2. We are clearly still pre-1.0.
It also doesn't make sense to append "(WARNING: BETA SOFTWARE)" to pre-releases such as alpha releases, which are to be considered _more_ unstable than beta releases.

documentation updates needed
In preparation for the v0.37 release, this PR updates:
1. The [release guidelines](https://github.com/tendermint/tendermint/blob/thane/pre-release-workflows/RELEASES.md#pre-releases) regarding alpha and beta versions, as well as release candidates.
2. The GitHub workflows to build all 3 kinds of pre-releases for:
1. Docker images
2. Binaries (I'm still not 100% sure whether this is necessary, but it does act as a clear signal to users that a pre-release is available, and pre-built binaries could be useful for people running testnets who don't use Docker)
3. The Goreleaser config to auto-detect whether a tag is a pre-release and mark it as such as the release is created on GitHub.
