Update the workflow "No Run" logo

Describe your changes and why you are making these changes

It now looks like this - is this better?

tbh I don't know if I love this look - if we're worried about it looking too much like a list, maybe something more neutral could work? https://fontawesome.com/icons/bars-staggered?f=classic&s=solid

ENG-2880

[ ] I have created a descriptive PR title. The PR title should complete the sentence "This PR...".
[ ] I have performed a self-review of my code.
[ ] I have included a small demo of the changes. For the UI, this would be a screenshot or a Loom video.
[ ] If this is a new feature, I have added unit tests and integration tests.
[ ] I have run the integration tests locally and they are passing.
[ ] I have run the linter script locally (See python3 scripts/run_linters.py -h for usage).
[ ] All features on the UI continue to work correctly.
[ ] Added one of the following CI labels:
- run_integration_test: Runs integration tests
- skip_integration_test: Skips integration tests (Should be used when changes are ONLY documentation/UI)
