Fix required explicit parameter name for Query docs

[Kilo-Loco]

What does this PR do?

Small changes to the Query method calls shown in the Swift docs.

The Query method signatures all follow a similar format to the snippet below:

public static func equal(_ attribute: String, value: Any) -> String {}

value is an explicitly named parameter which requires the call site to look like the snippet below:

Query.equal("title", value: "Avatar")
