[Backport] Fix instances of -Wmissing-template-arg-list-after-template-kw.

Clang has a new warning that requires a template argument list after using
the template keyword. Remove uses of the template keyword when we're not
specifying types.

See llvm/llvm-project#94194 for the upstream
clang change.
