Simplify use-package declaration for org-ql-search

We want `org-ql-search`, but need to install `org-ql`, so it's best to simply state
this in the `:ensure` declaration.

The `:commands` specification might be redundant, as `org-ql` comes with an
autoload file.  But let's keep it there for clarify purposes.
