Remove redundant reference WordPress.Security.EscapeOutput.OutputNotEscaped in WordPress-VIP-Go ruleset

[rebeccahum]

This reference is redundant:

VIP-Coding-Standards/WordPress-VIP-Go/ruleset.xml

Line 115 in 60ad148

<rule ref="WordPress.Security.EscapeOutput.OutputNotEscaped"/>

Because it is already inherited from parent WordPressVIPMinimum ruleset:

VIP-Coding-Standards/WordPressVIPMinimum/ruleset.xml

Line 20 in 60ad148

<rule ref="WordPress.Security.EscapeOutput"/>
