patch 8.2.1788: Vim9: still allows :let for declarations

    patch 8.2.1788: Vim9: still allows :let for declarations

    Problem:    Vim9: still allows :let for declarations.
    Solution:   Make the default for v:disallow_let one.  It can still be set to
                zero to allow for using :let.
