Improve dynamic DB docs

[cmeeren]

Closes #356

I wasn't able to generate the docs; there were warnings errors all over the place when executing the build script. I don't think they were related to my changes. Feel free to test yourselves. :)

Any chance to have a look at merging this?

Is this waiting for anything in particular? Anything I can do to help?

@cmeeren, waiting for someone to pull it , compile / check the doc, maybe play around with it, push new docs to git branch for it to be online.

In my case, I can't deal with it right now, and when I'll be able to do, it will be when I can allocate a large enough buffer of time to tinker with the library beside a small doc update.

If you have the docs compiled already, you can make a PR against https://github.com/fsprojects/FSharp.Data.SqlClient/tree/gh-pages which I will review / merge in shorter amount of time.

Hope that makes sense.

Thanks, I see. Unfortunately I haven't been able to compile the docs. No worries, take it on your own time. 👍
