TP GHA Fails: -bash: export: `demo3'': not a valid identifier

[zrhoffman]

This Bug Report affects these Traffic Control components:

• Automation - GitHub Actions

Current behavior:

Ever since #6265 (quoted variables that contain spaces in CDN in a Box's env file) was merged, the Traffic Portal Integration Tests GitHub Action has failed:

/home/runner/work/trafficcontrol/trafficcontrol/.github/actions/tp-integration-tests/entrypoint.sh: line 113: export: `demo3'': not a valid identifier
/home/runner/work/trafficcontrol/trafficcontrol/.github/actions/tp-integration-tests/entrypoint.sh: line 113: export: `Cole'': not a valid identifier
Child process " /home/runner/work/trafficcontrol/trafficcontrol/.github/actions/tp-integration-tests/entrypoint.sh " exited with status code 1 !

Expected behavior:

As of #6188, the Traffic Portal and Traffic Ops Integration Tests GitHub Actions no longer start Traffic Vault, Exporting variables from the CDN in a Box env file is no longer necessary, those lines can be removed.

Steps to reproduce:

[user@computer trafficcontrol]$ export $(<infrastructure/cdn-in-a-box/variables.env sed '/^#/d')
-bash: export: `demo3'': not a valid identifier
-bash: export: `Cole'': not a valid identifier
