feat: load default acknow list when init AcknowListSwiftUIView

[tisfeng]

Refer #124

    public init(acknowList: AcknowList? = AcknowParser.defaultAcknowList()) {
        self.init(
            acknowledgements: acknowList?.acknowledgements ?? [],
            headerText: acknowList?.headerText,
            footerText: acknowList?.footerText)
    }

This removed pods footer text, because here have both sources.

I didn't change a lot of the code, there were some code changes that were caused by IDE auto-formatting, so feel free to change that back if it matters to you.
