Incorrect default documented for mergeArrays option

[colinrotherham]

Module version

11.0.4

What documentation problem did you notice?

The type declarations for merge() have mergeArrays: false incorrectly set by default:

hoek/lib/index.d.ts

Lines 116 to 121 in 7309947

	/**
	* When true, array value from `source` is merged with the existing value in `target`.
	*
	* @default false
	*/
	readonly mergeArrays?: boolean;

But the source code (and documentation) shows mergeArrays: true as the default:

hoek/lib/merge.js

Line 20 in 7309947

options = Object.assign({ nullOverride: true, mergeArrays: true }, options);

This caught me out recently, I'll open a PR if that's alright

Thanks for the report! A PR would be welcome.

No problem @kanongil, fixed in #396
