GH-310 Relax input restrictions on quoted strings

[huanmeng-qwq]

Quoted strings should be an optional input method, rather than being able to only use " to input after the developer has defined annotations

@Command(name = "quoted")
class QuotedCommand {
    @Execute
    fun base(@Arg @Quoted arg: String) {
        /*
        /quoted 123
        arg = "123"
        
        /quoted "2345
        arg = "2345"
        
        /quoted "12345"
        arg = "12345"
        
        /quoted "12345 678
        arg = "12345 678"                        
        */
    }
}
