gnu: Add oils.

Since release 0.16.0 the former Oil project has been renamed to
Oils (https://www.oilshell.org/blog/2023/03/rename.html).  This patch
deprecates the old oil package in favor of a new oils package updated to
the latest version.  Additionally since release 0.21.0 Oils is
completely free from bundled Python code.

* gnu/packages/shells.scm (oils): New variable;
[source]: Remove mention of bundled Python sources, from release 0.21.0
it is no more the case;
[phases]: use Oils build system.
(oil): Deprecate in favor of oils.
