`auth:web:login --browser <name>` hangs when the browser you try to use isn't installed

[RodEsp]

Summary

To resolve https://github.com/forcedotcom/cli/issues/1465, the --browser flag was added to the auth:web:login command but with it a bug was introduced that causes the command to hang when you try to use a browser that isn't installed.

Steps To Reproduce:

1. Make sure you don't have either edge, chrome, or firefox installed.
2. Run sfdx auth:web:login --browser <nameOfBrowserThatIsNotInstalled>

Expected result

The command should exit with an error saying the browser is not available or installed or something like that.

Actual result

The command just hangs indefinitely until the process is manually killed by the user.

System Information

• Which shell/terminal are you using? Powershell 7, although I've seen this on bash too
• Which version of the CLI are you using? This is happening with version 2.3.0 of plugin-auth
