tests: use go-yq instead of python-yq

[gquintard]

will help with #117

[Copilot]

Pull request overview

Updates the chart unit-test suite to use Go yq (mikefarah/yq v4-style flags) instead of the Python yq wrapper, aligning test JSON extraction and type assertions across the charts. This supports ongoing work like #117 by making CI/test tooling more predictable and removing a Python dependency from the pipeline.

Changes:

• Replace Python-yq-style yq -r -c usage with yq -o=json -I=0 (plus -r where needed) across BATS unit tests.
• Adjust type assertions from jq-style (string/number) to go-yq tag outputs (!!str/!!int) where applicable.
• Remove pip install yq from CI (but CI still needs an explicit go-yq install; see comment).

LGTM, I rebased #117 off of this too.
