Improve instructions for commercial installer

[ddalcino]

Borrow code from @Kidev's excellent aqtinstall PR that teaches aqtinstall how to use the commercial installer, to improve the official command instructions here:

aqt-list-server/src/App.tsx

Lines 180 to 195 in 3ae82fa

	<CommandPanel
	id="official-command"
	label={
	<span>
	Your{" "}
	<a href="https://doc.qt.io/qtinstallerframework/ifw-use-cases-cli.html">
	official qt install
	</a>{" "}
	{state.isWindows() ? "powershell" : "bash"} command: (Please note
	that this command will require patience and CLI option wrangling to
	get it to work unattended)
	</span>
	}
	command={state.toOfficialInstallCmd()}
	isDisabled={!state.hasOutputs()}
