Build with ubuntu-20.04 rather than ubuntu-latest

[craigraw]

The currently released 3.0.0 Linux binaries fail on Ubuntu 20.04 with version 'GLIBC_2.35' not found.

There seems to be no particular reason to require Ubuntu 22.04 or later, and this could be fixed by changing the relevant runs-on parameter in workflow.yml from ubuntu-latest to ubuntu-20.04.

The release binaries use https://github.com/bitcoin-core/HWI/blob/master/contrib/build.Dockerfile and is separate from the github actions workflows. It uses debian bookworm, which is also fairly recent.

IIRC this was done because something stopped working with the previous target of oldoldstable, and every version in between, although I no longer remember what.

With the default installation, hwi won't work on 20.04. As a result, all who are using Wasabi with hardware wallets must have Ubuntu 22.04+ or update GLIBC. Is it possible to have a release that is working on ubuntu-20.04?
