This PR fixes an error in the v5 docs. The btn-close-white class actually uses the filter (not backdrop-filter)
## White variant
-Change the default `.btn-close` to be white with the `.btn-close-white` class. This class uses the `backdrop-filter` property to invert the `background-image`.

{{< example class="bg-dark" >}}
<button type="button" class="btn-close btn-close-white" aria-label="Close"></button>
- Renamed `.close` to `.btn-close` for a less generic name.
- Close buttons now use a `background-image` (embedded SVG) instead of a `×` in the HTML, allowing for easier customization without the need to touch your markup.
- Added new variables to better control the customization.
-- Added new `.btn-close-white` variant that uses `backdrop-filter: invert(1)` to enable higher contrast dismiss icons against darker backgrounds.
