forceMultiPart TypeScript Definition for Options

[KidSysco]

The forceMultiPart option is not available in TS, due to it missing from the definitions.

I added it to the FormMethodOptions definition, and I added two tests to help ensure the defs are working properly.

Let me know if you need any further changes to this PR and I will support it.

Fastify rocks!

Thank you.

Oh gosh - I forgot to add it to the readme! Would you be so kind to add it too?

A small bit of documentation has been added to what is there. It is not super verbose. I could certainly talk much more about it if needed. lol

But I have a feeling you want to keep it simple.

Let me know if you need anything else.
