Sync interval documentation for TheHive4-MISP connector

[dpreuveneers]

I followed the Connectors.md documentation to link a MISP instance with TheHive4. For testing purposes, I modified the interval: 1 hour configuration parameter to change the sync frequency, but after restarting TheHive4, the modification seemingly did not have any effect according to the log files (i.e. the sync frequency remained 1 hour).

However, in the TheHive-4.0.0 branch, I found a reference configuration file declaring two different configuration parameters that seem to be doing what I was looking for:

syncInterval = 1 hour
syncInitialDelay = 15 minutes

Is it possible that the TheHive4 Connectors.md documentation needs updating?
