fix(ci): install kustomize in deploy-dev job (#55)

* fix(ci): install kustomize in deploy-dev job

Add imranismail/setup-kustomize@v2 step so the deploy-dev job can
run kustomize edit set image without a "command not found" error.

Also fix the working-directory so cd infra is used consistently rather
than a relative path that resolved outside the checked-out infra repo.

* fix(ci): correct kustomize image name and tag in deploy-dev

- Remove '=' rename syntax which strips the GHCR registry prefix
- Use calver_tag output from build-and-push instead of github.sha
- Update commit message to reflect the correct tag

* fix(ci): add path: infra to checkout step so cd infra succeeds

CTO review feedback: actions/checkout@v4 must specify path: infra
so that subsequent 'cd infra' commands resolve to the checked-out
infra repository, not the cartsnitch repo root.

* fix(ci): cd into overlay dir before kustomize edit set image

CTO review feedback: kustomize edit set image operates on the
kustomization.yaml in the current working directory. Since the
target file is at infra/apps/overlays/dev/kustomization.yaml, the
step must cd there before running kustomize.
