An entity in copilot.vim docs is not highlighted

[231tr0n]

Hi OXY2DEV! I was going through the copilot.vim docs and found that an :Copilot_enable is not being highlighted by helpview.nvim. What do you think might be going wrong here?

To reproduce the issue:-

1. Paste the below script in a file called repro.lua and run it as 'nvim -u repro.lua repro.lua'.

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
	spec = {
		"nvim-treesitter/nvim-treesitter",
		"OXY2DEV/helpview.nvim",
		"github/copilot.vim",
	},
})

require("nvim-treesitter.configs").setup({
	auto_install = true,
})
vim.cmd("TSInstall vim vimdoc")
require("helpview").setup()

2. Run :h copilot. You can see that :Copilot_enable is not highlighted as shown in the below image.
