Expose via Web API

[lqdev]

Set up a Web API so users can use the library via a REST endpoint.

This is also useful for Docker scenarios as well.

Feel free to assign this one to me.

I started working on something like this but the moment I import from markitdown import MarkItDown I get the ugly warning:

python3.12/site-packages/starlette/routing.py:297: ResourceWarning: Unclosed file <tempfile.SpooledTemporaryFile object at 0x149021990>
  await self.app(scope, receive, send)
ResourceWarning: Enable tracemalloc to get the object allocation traceback

This is without even actually instantiating a MarkItDown object let alone using it. Is that a bug in the package?

Here's a web app I made that works with Markitdown. I use it for my personal workflow: www.docx2md.com

Great to see the community work and samples around this!

@elbruno also put together a quick sample of how such an API might be consumed in a C# client application.

Once #202 is merged, it'd be great to publish the Dockerfile as an image to the Microsoft Container Registry so you don't have to pull down the entire repo to use the container / server.
