Describe the issue

Current behaviour

Currently, $accordion-color is used to set the accordion button color through --#{$prefix}accordion-btn-color.

https://github.com/twbs/bootstrap/blob/fca04c07131a81e625a516cf7b98a8c7df0df1c1/scss/_accordion.scss#L16 However, I expected $accordion-button-color to be used here, which currently only is used as a value for $accordion-icon-color.

I also expected $accordion-color to change the accordion body color, which is currently not the case, but already got fixed in PR #36921.

Expected behaviour

I would expect the $accordion-button-color variable to change the color of the accordion button and $accordion-color to change the color of the accordion body.
