option is `symbol_folding.auto_unfold` with keys `hovered` and `only`.
Key `hovered` is the successor of the legacy `symbol_folding.auto_unfold_hover`
option. **The old option would still work as expected.**
- Updated the default symbols icon highlights to not use highlight groups that
start with `@`. Everything should still work as expected, most highlights
should still be the same. This is to support `nvim-0.7`. The symbols icon
highlights is still configurable as before.
- Highlights used by outline.nvim are now set to default using links if they
aren't already defined. Default winhl for outline window is now an empty
string, and for preview window, `NormalFloat:` to ensure the preview window
looks similar to a normal window (since it displays a preview of the actual
code)
- Highlights will also take into account `ctermfg/bg` when setting default values.
This ensures outline.nvim highlights work if `termguicolors` is not enabled
