feat(modal): remove replace usage

- Remove `replace: true` usage

BREAKING CHANGE: This removes `replace: true` usage, causing some structural changes to the HTML - the major part here is that there is no more backdrop template, and the top level elements for the window/backdrop elements lose a little flexibility. See documentation examples for new structure.

Closes #5989
