Comment corrections and two functions reordered

Misspellings:
"beginnign" changed to "beginning",
"Insert one of several lines" changed to "Insert one or several lines" in two functions,
"identation" changed to "indentation",

Missing comment copied from the function that inserts a line
in the opposite direction:
(defun spacemacs/insert-line-below-no-indent (count)
"Insert a new line below with no indentation."
and renamed the direction, resulting in:
"Insert a new line above with no indentation."

Duplicate comments removed, the comments inside the functions,
are better explanations of what the function does.

Functions reordered:
The functions:
(defun spacemacs/evil-insert-line-below (count)
and
(defun spacemacs/evil-insert-line-above (count)

were written in a illogical order,
the "above" function should be written before the "below" function,
with this change, the function order will match other functions
with "above" and "below" in their names,
for example these:
(defun spacemacs/insert-line-above-no-indent (count)
https://github.com/syl20bnr/spacemacs/blob/develop/layers/%2Bdistributions/spacemacs-base/funcs.el#L535
(defun spacemacs/insert-line-below-no-indent (count)
https://github.com/syl20bnr/spacemacs/blob/develop/layers/%2Bdistributions/spacemacs-base/funcs.el#L549
