Subject: [PATCH] fix(term_preview): bad `bat` command generation (#3256)

Using `bat` would result in the command being a nested list.

eg. using `:Telescope plaents` with `bat` installed
```
{
  "bat",
  { "--pager", "less -RS" },
  "--style=plain",
  "--color=always",
  "--paging=always",
  "--",
  "/home/jt/projects/telescope.nvim/data/memes/planets/earth",
}
```

This would cause `vim.fn.termopen` to throw an error as the command is
expected to be a flat list or string.
