Hello，thanks for your works, the directory function works very well, but I find that the CodeTheme parameter cannot be used. May I ask how to configure this parameter now? Also, do you think we need to update Readme.md, add more examples, and demonstrate the usage of each parameter?

@0use-TE This property has been moved to Styling in #320.

MudBlazor.Markdown/samples/MudBlazor.Markdown.Core/MarkdownPage.razor

Lines 4 to 11 in 3aab1b3

	<MudMarkdown
	Value="@Value"
	Styling="Styling"
	OverrideLinkUrl="OverrideLink"
	OverrideHeaderTypo="OverrideHeaderTypo"
	HasTableOfContents="HasTableOfContents"
	TableOfContentsHeader="Table of contents" />

MudBlazor.Markdown/samples/MudBlazor.Markdown.Core/MarkdownPage.razor

Lines 25 to 35 in 3aab1b3

	private MudMarkdownStyling Styling { get; } = new()
	{
	Table =
	{
	CellMinWidth = 100,
	},
	CodeBlock =
	{
	Theme = CodeBlockTheme.DraculaBase16,
	},
	};

Also, do you think we need to update Readme.md, add more examples, and demonstrate the usage of each parameter?

I am planning to create a wiki page for it, README would become too large if all properties are listed there.
