Bug: Build name mismatch breaks CI dependency references

The data9build step was renamed to data9build-multipy, but the "arrow v9 tests" and "arrow v9 tests (data_non_parallel)" still reference the original data9build name. This occurs in both their depends_on fields and the --build-name argument within their commands, causing CI failures due to missing build steps and artifacts.
