[Bug]: highlights are not fully reloaded on ColorScheme autocmd

### Is there an existing issue for this?

- [x] I have searched the existing issues

### What happened?

I'm using [vscode](https://github.com/Mofiqul/vscode.nvim) theme with [auto-dark-mode.nvim](https://github.com/Mofiqul/vscode.nvim) plugin to sync nvim theme with OS dark mode preferences.

After switching vscode styles between dark and light themes, I call `vim.cmd('doautocmd ColorScheme')` to trigger highlights reload.

The bufferline reacts to `ColorScheme` event but does only partial highlights reload.\
Some highlights are still out-of-date, which causes a following appearance bug:

*Switched from light to dark*

Here is a sample of highlights that are out of date:

### What did you expect to happen?

Bufferline fully reloads its own highlights when `ColorScheme` autocmd is fired.

As workaround, I tried to manually remove old highlights and reload them as plugin does under the hood:

```lua
local all_highlights = vim.api.nvim_get_hl(0, {})

for name, _ in pairs(all_highlights) do
if name:match('^BufferLine') then
vim.api.nvim_set_hl(0, name, {})
end
end

local kfg = require('bufferline.config')
kfg.update_highlights()
```

Unfortunately this just removes highlights, but doesn't restore them.

### Config

```lua
{
'akinsho/bufferline.nvim',
version = '^4.9.1',
dependencies = {
'nvim-tree/nvim-web-devicons',
},
---@module 'bufferline'
---@type bufferline.userconfig
opts = {
options = {
mode = 'buffers',
diagnostics = 'nvim_lsp',
offsets = {
-- possibly dapui_stacks, bapui_breakpoints, dapui_scopes, dapui_console, dap-repl
{
filetype = 'neo-tree',
text_align = 'left',
separator = true,
},
{
filetype = 'dapui_watches',
text_align = 'left',
separator = true,
},
},
},
},
init = function()
vim.opt.termguicolors = true
end,
},
```
