Support rendering collection of values

[darrelmiller]

We can add support by adding a key-value pair for each item in the collection. As per the HTML specification, the data model is a list of name-value tuples https://url.spec.whatwg.org/#urlencoded-serializing
There is no requirement for the name to be unique. This allows us to represent arrays by repeating the key name for each array value.

public void WriteCollectionOfObjectValues<T>(string? key, IEnumerable<T>? values) where T : IParsable => throw new InvalidOperationException("Form serialization does not support collections.");

@andrueastman would you mind tackling this one please? It should be a fairly easy implementation
Also I think @darrelmiller meant this method since we don't serialize nested object values.
