GPG signature timeout on retrieval on self-hosted runner

[iconicaladb]

Describe the bug
This is the same issue as #656 and #690 however I've narrowed this down to failing on self-hosted runners but working on GitHub-hosted runners.

When run on the GitHub-hosted runners (ubuntu-latest), the following debug logs show a successful run:

##[debug]ℹ️ Verifying environment...
##[debug]✅ Environment verification completed...
##[debug]ℹ️ Downloading CC Reporter from https://codeclimate.com/downloads/test-reporter/test-reporter-latest-linux-amd64 ...
##[debug]✅ CC Reporter downloaded...
##[debug]ℹ️ Verifying CC Reporter checksum...
##[debug]✅ CC Reported checksum verification completed...
##[debug]ℹ️ Verifying CC Reporter GPG signature...
##[debug]✅ CC Reported GPG signature verification completed...

When run on self-hosted runners, the following debug logs show the binary is downloaded successfully but not the subsequent PGP public key (the timeout is instantaneous, and the step completes in 3s):

Node.js v20.19.0

Both run the following action:

    - name: Execute tests and coverage
      uses: paambaati/codeclimate-action@v9.0.0
      env:
        CC_TEST_REPORTER_ID: ${{ env.CC_TEST_REPORTER_ID }}
      with:
        coverageCommand: pipenv run pytest --junit-xml=myapp-test-results.xml --cov=myapp --cov-report term-missing --cov-report xml tests

execing into the running self-hosted container and running curl works successfully so connectivity to keys.openpgp.org is fine.
