[FIX] website: change the asset disabling from GC to CRON

Before this commit, the behavior disabling the unused snippet assets was put
directly in the autovacuum CRON instead of its own CRON.

That behavior is leading to some perf-issue running the autovacuum cron since
it would take too much time.
Indeed, the code will loop inside as many snippet as it exists, and every time
then perform an SQL Query to get the HTML fields using the snippet.

An improvement will come later to not loop on every snippet anymore.
