Update deps and WPCS before release

[kasparsd]

• Update Node and Composer deps.
• WPCS formatting prior release.
• Switch to MariaDB containers to make it compatible with ARM Macs.

Looks like #1264 made one of the unit tests for EDD fail:

1. WP_Stream\Test_WP_Stream_Connector_EDD::test_log_override
   Failed asserting that 2 is identical to 4.

stream/tests/tests/connectors/test-class-connector-edd.php

Lines 172 to 193 in 305583d

	public function test_log_override() {
	// Callback for validating expected log data.
	$asserted = 0;
	add_action(
	'wp_stream_log_data',
	function( $data ) use( &$asserted ) {
	if ( 'edd' === $data['connector'] && in_array( $data['context'], array( 'downloads', 'discounts' ), true ) ) {
	$asserted++;
	}
	return $data;
	},
	99
	);
	// Create download and discount to trigger logs.
	$this->create_simple_download();
	$this->create_simple_percent_discount();
	// Check assertion flage
	$this->assertSame( $asserted, 2 );
	}

I'm not sure why the wp_stream_log_data is called twice for every post insert.

This was causing the wp_stream_log_data action to be called twice -- once for the EDD connector and once for the Posts connector and the test in this file was being run during both.
