salted_hmac() docstring shouldn't mention hashlib.new().

[Francisco Couzo]

On its documentation, it mentions "any algorithm name supported by hashlib.new() can be passed",
but this is not true, algorithms supported by hashlib.new() may not accessible through getattr,
This was mentioned here:
​https://github.com/django/django/pull/12291#discussion_r364348132
But it wasn't addressed.

Either we can make salted_hmac use hashlib.new (which is discouraged by python's documentation).
Or change the documentation to not mentioned hashlib.new.

[Mariusz Felisiak]

Agreed. I would remove new() from the docstring:

-    but any algorithm name supported by hashlib.new() can be passed.
+    but any algorithm name supported by hashlib can be passed.
