fix: Align autoLaunch capability behaviour with iOS

[mykola-mokhnach]

iOS does app install, but does not launch it, which makes more sense in the capability name context.

Seems good.

appium-uiautomator2-driver/lib/driver.js

Lines 419 to 423 in 819a064

	if (this.isChromeSession) { // start a chromedriver session
	await this.startChromeSession(this);
	} else if (this.opts.autoLaunch && this.opts.appPackage) {
	await this.ensureAppStarts();
	}

is responsible for launching the app under test
