Improve testing on Go-tip

[yurishkuro]

We have a CI workflow that runs only on the main branch commits that in addition to regular unit tests runs them on gotip version of Go. Recently it started failing because it cannot download Go tip by commit hash, perhaps due to some upstream failure to build the distro.

The gotip installation is done by this action .github/actions/setup-go-tip/action.yml:

Proposal:

• split this action into two steps:
  • first step to try to download the gotip distro and export a success/failure status (via echo "{name}={value}" >> "$GITHUB_OUTPUT")
  • second step to run only if previous step was successful and attempt to install the distro
• add a third step to run only if step 1 failed and use a slower way to install (build) gotip: https://pkg.go.dev/golang.org/dl/gotip

In order to test the changes, I'd recommend implementing them first in a test project, similar to https://github.com/yurishkuro/test-project-3/tree/master/.github.
