build(vim-patch): Vim9 comment plugin is N/A (#37370)

Nvim has builtin 'gc' commenting, instead of bundling
https://github.com/tpope/vim-commentary, partly for treesitter.
Vim9 comment plugin, runtime/pack/dist/opt/comment/ seems to be based on
https://github.com/habamax/.vim/blob/master/autoload/comment.vim
which is similar to vim-commentary.

test/functional/lua/comment_spec.lua has enough tests to justify
skipping test_plugin_comment.vim.
Vim's terminal + packadd + Vim9 test files is a chore to manually port.
