Prevent 'scribble/acmart' documents from loading the 'tocstyle' package,
because this package conflicts with 'acmart.cls'.
(Specifically, 'tocstyle' should be loaded before 'hyperref', but 'acmart.cls'
loads 'hyperref'.)
Without 'tocstyle', Scribble's 'table-of-contents' function produces an OK
table of contents.
