CICD: Integration test output not visible

[TomOnTime]

Fixes #4233
Fixes #4227
Fixes #4220

Issue

Issue 1: The output of the integration tests isn't displayed anywhere. It seems that the output is generated (provider tests take the right amount of time) but I don't see anyplace in the UI that I can view the results.

• Example:
  https://github.com/DNSControl/dnscontrol/actions/runs/25500999681/job/74833580403

Issue 2: The code that sets "END" is failing with a if [[ not found error.

Resolution

• Issue 2: It turns out the code to generate $END is using if [[ which is a bash-ism, and this GHA defaults to sh. Change to the bash shell for that step.

@chicks-net @cafferata: I'm stumped. It's probably something obvious. I see the output collected in ${TEST_RESULTS}/gotestsum-output.txt but I don't see any code that gives it to GitHub to display it. Any thoughts?

@TomOnTime The output was visible before #4153 (March 11). That PR added the > ${TEST_RESULTS}/gotestsum-output.txt redirect to the gotestsum command, which sends all stdout to the file instead of the Actions log. The file gets uploaded as an artifact, but there's nothing that prints it back to the log.

I verified this by downloading the full job log archive for this PR's run:
https://github.com/DNSControl/dnscontrol/suites/67915295585/logs?attempt=1

Looking at the TRANSIP job log, there's a 10 minute gap between END: Using: END=999 and the upload-artifact step. The tests ran, but all output went to the file.

The fix for Issue 1 would be to replace > with | tee:

gotestsum ... ./... 2>&1 | tee ${TEST_RESULTS}/gotestsum-output.txt

This writes to both the file (for the artifact) and stdout (for the Actions log).
