Change the "Name" property to "Model" under OllamaSharp.Models

[mili-tan]

Hi, there
I just found some changes while checking https://github.com/ollama/ollama/blob/main/api/types.go and they are look like:

	// Name is deprecated, see Model
	Name string `json:"name"`

should we also make some changes to align with upstream?

(btw, I'm not a native English speaker, so sorry for my English if there are some mistakes or weirdness)

Oh, nice find. Would you add this to the current pull request?

[mili-tan]

Is it better to change “Name” directly to “Model” or add “Model” and mark the original “Name” as obsolete, or just only change the JsonPropertyName?

[awaescher]

I would love to do mark Name as obsolete so that the devs don't face breaking changes for this

[mili-tan]

I added some changes, #38

Once again, thanks for contributing!
