* chore(ci): fix typo in restrict presubmit samples ITs to only snapshot

Fixes below error in Java repos when googleapis/synthtool#804 was merged:
```
github/java-bigquerystorage/.kokoro/build.sh: line 81: pushd: {SAMPLES_DIR}: No such file or directory
```

Thanks @kolea2 for spotting this in Fusion build logs.
