text-object: remove text_object_number

This was only used by the number increment/decrement action.
The same functionality (and more) can be implemented in lua
using something like:

 vis:textobject_new("in", function(win, pos)
  return win.file:match_at(vis.lexers.integer + vis.lexers.float, pos, 64)
 end, "Number text object")
