[BUG] mismatch between documentation and requests

[fmigneault]

Documentation indicates some 'current' user routes as valid (example below, maybe others also)
https://pavics-magpie.readthedocs.io/en/latest/api.html#tag/Logged-User%2Fpaths%2F~1users~1current%2Fput

But this is clearly forbidden here:

Magpie/magpie/api/management/user/user_views.py

Lines 67 to 70 in 10849ba

	user_name = ar.get_value_matchdict_checked(request, key="user_name")
	ax.verify_param(user_name, param_compare=get_constant("MAGPIE_LOGGED_USER"), not_equal=True,
	http_error=HTTPBadRequest, param_name="user_name", content={u"user_name": user_name},
	msg_on_fail=s.Service_PUT_BadRequestResponseSchema_ReservedKeyword.description)
