Running NIST crawler after ~year deletes data dir

[kesara]

The NIST crawler for bib.ietf.org was disabled due to inactivity ¹
When I manually ran it today it deleted the /data dir because GHA removed all the NIST data files. ².

@kesara the crawler removes the data before fetching updated dataset. This problem occurred because the script caught any fetching errors, so the script finished without errors even fetching failed.

The error catching is removed in relaton-nist v1.19.3. With the last version fetching errors will end the script and GHA running, so the empty data dir won't be committed.

@andrew2net thanks for the quick fix.
bibxml-service has been using relaton nist v1.14.*.
I'll update the Gem, hopefully things won't break.
