Docs: add more functions missing from lists

[jrfnl]

Looking at the Brain\Monkey\Functions\stubTranslationFunctions() function, the _e() and _ex() functions are actually also stubbed.

BrainMonkey/inc/api.php

Lines 134 to 157 in dbb41d3

	/**
	* Stub translation functions.
	*
	* @see EscapeHelper
	*/
	function stubTranslationFunctions()
	{
	stubs(
	[
	'__',
	'_x',
	'translate',
	'esc_html__' => [EscapeHelper::class, 'esc'],
	'esc_html_x' => [EscapeHelper::class, 'esc'],
	'esc_attr__' => [EscapeHelper::class, 'esc'],
	'esc_attr_x' => [EscapeHelper::class, 'esc'],
	'esc_html_e' => [EscapeHelper::class, 'escAndEcho'],
	'esc_attr_e' => [EscapeHelper::class, 'escAndEcho'],
	]
	);
	when('_e')->echoArg();
	when('_ex')->echoArg();
	}
