chore(linter): bump timeout limit (google#3707)

OSV-schema added JSON schema checks which increased the runtime of
OSV-linter. To address linter timeout issues, we can either increase the
timeout limit or download all.zip files from different ecosystem buckets
and run OSV-linter in multiple threads.

For now, I will simply increase the timeout limit first, as the cron job
only runs once a day and JSON schema checks should only increase the
runtime slightly. Let's see how long it takes before splitting it into
multiple threads.
