Chrome: qz:launch shows pop-up

[tresf]

At some point, our code to suppress the qz:launch pop-ups stopped working.

Initial glance would blame the deprecation of URLWhitelist, but changing this to URLAllowlist doesn't seem to fix the symptom.

• ⚠️ https://chromeenterprise.google/policies/#URLWhitelist
• ✅ https://chromeenterprise.google/policies/#URLAllowlist

Code:

• Mac:
  

  tray/src/qz/installer/MacInstaller.java

  Line 70 in 291200f

  ShellUtilities.execute("/usr/bin/defaults", "write", plist, "URLWhitelist", "-array-add", DATA_DIR +"://*");

• Linux:
  

  tray/src/qz/installer/LinuxInstaller.java

  Line 30 in 291200f

  public static final String CHROME_POLICY = "{ \"URLWhitelist\": [\"" + DATA_DIR + "://*\"] }";

• Windows:
  

  tray/src/qz/installer/WindowsInstaller.java

  Line 148 in 291200f

  WindowsUtilities.addNumberedRegValue(HKEY_LOCAL_MACHINE, "SOFTWARE\\Policies\\Google\\Chrome\\URLWhitelist", String.format("%s://*", DATA_DIR));

With regards to whether or not the "Always allow" checkbox is shown, there's a policy for that as well, which we don't currently configure:

• https://chromeenterprise.google/policies/#ExternalProtocolDialogShowAlwaysOpenCheckbox

Historically, we've suppressed this pop-up via policy, but recent version of Chrome seem to show this pop-up:

Changing line 70 to "URLAllowlist" did work for me. Do you see a policy listed under Chrome Policies on chrome://policy/

Great, let's get a PR prepared and then we can retest.
