SPIDERMON_MONITOR_SKIPPING_RULES only works with SpiderCloseMonitorSuite

[VMRuiz]

The SPIDERMON_MONITOR_SKIPPING_RULES setting is currently only used within SpiderCloseMonitorSuite, limiting its functionality to suites that extend from it:

spidermon/spidermon/contrib/scrapy/monitors/suites.py

Line 61 in d7d553a

if dict(crawler.settings).get("SPIDERMON_MONITOR_SKIPPING_RULES"):

This limitation is not mentioned in the documentation. It would be useful to extend this feature to all monitor suites.
