Describe the bug

After 1975116 and 1975116 were merged the tests/card.test.js` now fails. This is strange since these commits do not change any of the code that is tested. See https://github.com/anuraghazra/github-readme-stats/runs/7215331182?check_suite_focus=true.

Expected behaviour

The test should pass (See https://github.com/anuraghazra/github-readme-stats/runs/7020934858?check_suite_focus=true). @anuraghazra, did you encounter this problem before? It seems that the latest release of ubuntu-latest breaks the test. The stop element inside lineargradient is no longer found by querySelector method.
