Allow filtering and sorting on dictionary properties when using MartenDB provider

Product

Hot Chocolate

Is your feature request related to a problem?

The following is a valid MartenDB query and works if invoking manually

public class Player 
{
    public required Dictionary<Skill, int?> Skills { get; set; } = new();
}

await using var session = store.QuerySession();

  return session
      .Query<Player>()
      .Where(x => x.Skills[Skill.Pace] > 85)
      .OrderByDescending(x => x.Skills[Skill.Pace]);

This does not however work when invoking from hot chocolate query

skills: { all: { key: { eq: PACE }, value: { gt: 85 } } }

 "extensions": {
        "message": "Property 'Demo.Skill Key' is not defined for type 'Demo.Skill' (Parameter 'property')",
 }

There also seems no way of sorting on the keys of the dictionary since the dictionary is not defined as sortable even though all other properties on the document is sortable

The solution you'd like

It would be nice if there would be an similar approach of achieving this

Filtering

skills: { all: { key: { eq: PACE } value: { gt: 85 } } }

Sorting

order: [{ skills: { key: PACE direction: DESC }]

The issue names no files or tests. Start by reproducing the MartenDB provider query with dictionary filtering and sorting, then trace Hot Chocolate's filtering and sorting integration for dictionary properties. Done means the shown filtering and sorting GraphQL shapes work for the Skills dictionary without the reported property error.
