Normalize file naming conventions of directories and markdown files

[JeremyMcCormick]

Decide whether to use underscores or dashes in file names.

I suggest to use dashes rather than underscores as this is the more common convention.

It would also be appropriate to simply remove spaces entirely, and use instead file names like gettingstarted, instead of getting_started, etc.

I haven't a strong opinion on what solution to choose.
My only comment stays: this will break links here and there (e.g. wiki).
I consider that a minor thing that will solve itself over time.

With a site redesign, it would be expected that many links to subpages will be broken, but I don't think that is a reason not to proceed and make the paths and file names more consistent.

A common practice in Hugo to build automatically anchors is to replace spaces (and non alpha numerical characters) with a dash. This would make getting-started.

Then, to be consistent with the choice of Hugo, I would prefer the solution to not get rid of spaces but replace them with dashes. Besides, I find it more readable by human eyes (you still see a separation between words ; so, you see more clearly words which makes it more readable).

I am fine with using dashes for readibility instead of getting rid of spaces between words entirely.
