Rune Lillesveen 3411c66858 Bug 2010893 [wpt PR 57211] - Update spec references in tests for css-scoping/, a=testonly
Automatic update from web-platform-tests
Update spec references in tests for css-scoping/

The css-scoping spec has been moved to css-shadow.

Update all spec URIs in wpt tests. Also move some URIs from TR to
drafts.csswg as the new location is not published as a WD yet.
