fix(man.lua): skip Attrs.None highlights #32262

Browse Source 
Before the 7121983c45 refactoring this
loop added highlights from a `buf_hls` list that had filtered out
elements with `Attrs.None`. After the refactoring this added highlights
from `hls` directly, and those elements would fail with e.g.:

    $ nvim 'man://math.h(0)'
    Error detected while processing command line:
    Error executing Lua callback: /usr/share/nvim/runtime/lua/man.lua:205: Invalid 'hl_group': Expected Lua string
    stack traceback:
