feat(tekton/v1): propagate git-url into package publish tasks to label OCI/image artifacts (#4575)

## Summary
- pass `git-url` from the build-package linux/darwin pipelines into the
binaries/images tasks
- feed `git-url` into the generated packaging scripts as the 11th
argument
- export `GIT_URL=$(params.git-url)` in publish/build-and-publish so OCI
source labels resolve to the pipeline input

## Validation
- `yq eval .` on the 5 modified Tekton YAMLs
- `git diff --check`
