Not working for Alfred 5

[IamTheFij]

It looks like the library determines that Version 4 is being used because we're using the non-numbered Alfred folder. This folder is apparently used for all new versions.

Two possible fixes:

• Use the max version found in the version keys in that file
• Always use "current"

I'm leaning towards the latter.

For the time being, I'm working around this with:

func InfoWithVersion(v int) build.Option {
	return func(i *build.Info) {
		i.AlfredMajorVersion = v
	}
}

func init() {
	var err error
	if info, err = build.NewInfo(InfoWithVersion(5)); err != nil {
		panic(err)
	}
}

If it works well enough with 0 as the version, then the current approach should work.

Additionally, this can be worked around with no code change and setting the version in the environment before running the build. Eg. env alfred_version=5 mage build
