Description: fix the build against fmtlib 11
 Two incompatibilities introduced by fmtlib 11:
 .
  * fmt::join moved out of fmt/format.h into fmt/ranges.h, so fmt_writer.h has
    to include the latter explicitly. The header exists in fmtlib 10 as well,
    so this keeps building against the fmtlib currently in unstable.
  * basic_string_view's constructor taking a bare const char* is now guarded
    by FMT_CONSTEXPR20, so it is only constexpr when compiling as C++20 or
    later; fmtlib 10 guarded the same constructor with FMT_CONSTEXPR_CHAR_TRAITS,
    which is already constexpr in C++17. This package builds as C++17, so the
    constexpr array of string_view_t that spdlog builds out of
    SPDLOG_LEVEL_NAMES can no longer be initialised from bare string literals.
    Pass explicit lengths, exactly as spdlog's own SPDLOG_LEVEL_NAME_* macros
    do; the emitted level names are unchanged.
