fix: Flaky tests when run in GitHub Actions Workflow

[jessicatarra]

Description

Hey everyone! I initially attempted to resolve this issue by following the approach mentioned in this issue by setting the environment variable PUB_SUMMARY_ONLY=1 in the workflow. However, this did not work as expected.

Then, I decided to solve it by updating the ignoringDependencyMessages method in the matcher file, and this approach seems to be working fine.

Changes:

• Remove unnecessary TODO comment in the workflow file
• Update test command in workflow to remove unnecessary || true
• Update dependency messages matcher in matchers.dart test file

Super, thanks! Windows still seems to fail, but that might be unrelated?
