Josh Siviour 8205f88b04 ci: build sibling repos from a co-named branch, falling back to dev (#550)
The Build/Lint/Race jobs checked out viperblock and predastore at a hardcoded
ref: dev and overlaid them with a go workspace, so the go.mod pins were ignored
and a spinifex change depending on an unmerged sibling change could never
compile in CI. Resolve each sibling to a branch of the same name when it exists
on that repo, else dev, mirroring the e2e path in
scripts/tofu-cluster/build-install-artifacts.sh so unit CI and e2e CI agree.

# Resolve which branch of each sibling repo (viperblock, predastore) the CI
# workspace should build against. A cross-repo change is developed on a branch
# of the SAME name in each repo; build against that branch when it exists so the
# set can be tested together, and fall back to dev otherwise. This mirrors the
# resolution the e2e path already does in
# mulga/scripts/tofu-cluster/build-install-artifacts.sh, so unit CI and e2e CI
# agree on how sibling branches are selected.

# Reads $BRANCH (the triggering head/ref name) and writes viperblock=<ref> and
