[FEAT]: Codespaces: Add support for creating codespaces and get machine types

[Aaron-Junker]

Describe the need

This will allow Octokit to generate new codespaces with available machine types from a repository.

A possible implementation could be a function with the signature Codespace GitHubClient.Codespaces.Create(string repoOwner, string repoName, Machine machineType, string ref="main", CodespaceLocation? location= null, string? displayName = null)

CodespaceLocation is an enum with the values EuropeWest, SoutheastAsia, UsEast, UsWest

To get available machine configurations you could run a function with the signature: MachineCollection GitHubClient.Codespaces.GetAvailableMachines(string repoOwner, string repoName, string? ref=null)

MachineCollection will be a new type that can save multiple Machine objects.
