To prevent unwanted surprises with new minor versions of go, lock the
version to minor version using [semver tilde
syntax](https://github.com/npm/node-semver#tilde-ranges-123-12-1). We
were already getting 1.21.0 since yesterday, so use that version now as
minimum.
The `setup-go` actions did not all have `check-latest` which means they
use some cached version of go that currently still resolves to go1.20.4,
as seen in a number of recent runs that currently fail at govulncheck
because of it:
````
Run actions/setup-go@v4
Setup go version spec >=1.20
Attempting to resolve the latest version from the manifest...
matching >=1.20...
Resolved as '1.20.4'
````
Add the
[check-latest](https://github.com/actions/setup-go#check-latest-version)
option which should guarantee that this cache is skipped.
- Remove actions name where command is descriptive enough
- Use kebab-case instead of snake-case for step names
- Use shorter job names because to make PR checks more readable
- Remove duplicate `checks-backend`

Move drone cron pipelines to (GitHub) Actions. As these are mostly
compatible with Gitea Actions, when we start to dogfood, these will
already be migrated.
