Override typo for body

[Harmen02]

Is it possible to use Typo.body2 for body text instead of Typo.body1? For headings it is possible to override the typo with the MudMarkdownProps, can we do something like that for the body as well? That would be great.

I will try to implement it. Typo must be overridden on all MudText elements, so it might lead to bugs because there are many of them and I might miss something out.
