test(build): Use fixed version override for deterministic test fixtures

Solves the maintenance problem where the test fixture SHA would change
with every CLI version release. Now uses SENTRY_CLI_VERSION_OVERRIDE
environment variable to set a fixed version (0.0.0-test) in tests,
ensuring stable SHA checksums across releases.
