[Tagging] change recommendation from "depth" to "length" for the adit length?

[Martin Koppenhoefer]

I have now changed the tag name from "depth" to "length", as there haven't
been any more comments and the definition already said it was about
"length".

Bonus question, why not map adits optionally as ways? Shouldn't the tag be
"man_made=adit_portal" if only the portals are mapped and only nodes are
"allowed"?
