bump version to 12.2.2-pve1

/*!
@file
Adapts `boost::fusion::tuple` for use with Hana.

In the current version of Boost.Fusion, `boost::fusion::tuple` is basically
an alias to `boost::fusion::vector`, so both data types share the same
implementation in Hana.

    //! tuple, although the complexity of some operations might differ from
    //! that of a tuple.
