[AsmPrinter] Rename a comment of .debug_gnu_pubnames entry

Summary:
The comment refers to the field as "Kind:". However, in gdb,

https://sourceware.org/gdb//onlinedocs/gdb/Index-Section-Format.html names it "attributes",
gdb/dwarf2read.c:dw2_symtab_iter_next refers to the whole value as "cu_index_and_attrs"

Change it to `Attributes:` for consistency.
