Add preview for markdown fields like description

[jonastg]

Does it make sense to have a preview for fields that supports markdown in order to visualize how it will be?

That could be interesting, and I'm super used to the preview in the github comments (mainly to see how the comment looks like when I insert a lot of this and some images), but I'm a bit unsure about it is a real need yet in vlctechhub...because I'm not sure those text areas are the more comfortable option when dealing with complex / long texts and markups (as some job descriptions have), or it is better to go to an online markdown editor, write a lot of stuff there and then copy it.

I'd like to ask the people using the markdown in those fields about how they use it first.
