Fix t.references validating options on Rails < 7.1

Option validation was [added][1] for 7.1+ Migration classes, and a
compatibility layer was added to ensure that previous Migration versions
do not have their options validated. However, the `t.references` method
was missing in the compatibility layer which results in pre 7.1
Migrations validating options passed to `t.references`.

This commit fixes the issue by adding t.references to the compatibility
layer.

See also a [similar fix][2] for `add_reference`
