[DOCS] Document event_match_type option for master and minion configuration files

[ScriptAutomate]

Description

This was discovered as part of working on #58112

How is event_match_type used, when listed in the minion and master config files?

salt/conf/minion

Lines 929 to 932 in 8afbb8e

	###### Miscellaneous settings ######
	############################################
	# Default match type for filtering events tags: startswith, endswith, find, regex, fnmatch
	#event_match_type: startswith

Suggested Fix

Define how it is used, and what the available values mean, at least somewhere in the master and minion docs (*.rst files)

• startswith
• endswith
• find
• regex
• fnmatch

Type of documentation

• minion/master configuration files
• Salt Documentation (.rst) for master/minion configuration files
