test: keep the step-0 contract sequence linear

scripts/test.sh labels its pre-build contracts as a running 0a..0u sequence.
The new blob-generator contract was slotted in as "0f2" to sit next to the
other build-tooling contract, which breaks the one convention the list has.
Append it as 0v instead; these steps all run before the build, so position
carries no meaning beyond the label.
