support Nvim 10.0 new "LspInlayHint" and "WinSeparator"

[dupeiran001]

as shown here:

after changing my Nvim to 0.10.0 preview, I found the win separator become a white line, and the inlay hint color is almost invisible when selected.

Maybe should change win separator fg to background color, and inlay hint to a lighter grey?

Nvim version:

$ nvim -v
VIM v0.10.0-dev-2488+g5d4e1693c
Build type: RelWithDebInfo
LuaJIT 2.1.1707061634
Run "nvim -V1 -v" for more info

this is my Nvim config: dot files

Seems this repo isn't actively maintained anymore...

Here's my quick fix, using the same hl as comments, good for me

      require('nord.util').highlight('LspInlayHint',
        { fg = colors.nord3_gui_bright, style = 'italic' }
      )
