Vim has recently been updated to v9.0 in the image. The coloured syntax highlighting is not working for me and vim is monochrome.

Vim is recognising the filetypes correctly (:set filetype?). Looking at the colorscheme support (:colorscheme , CTRL+D), there is only desert in there.

I installed vim 9.0 into Ubuntu on WSL2 and colorscheme support was fine there.

Is there something that needs to be done to add the colorscheme support back in for the container?
