Revamp accordion borders to fix pixel jumping (#33149)
- Pushes the borders to the .accordion-item
- Simplifies the .accordion-flush
- Recreates the .accordion-button border-bottom with an inset box-shadow
- Updates background-color to solid to match other components like list group and prevent stacked translucent borders
- Use negative margin to overlap the consecutive items
