[ruby/openssl] asn1: adjusting an ASN1 test to use CONTEXT_SPECIFIC

AWS-LC's ASN1 parsing capabilities led to us examine some of our
ASN1 tests. One test in test_asn1.rb happens to use a tag number
of 8224. There are concerns with larger UNIVERSAL tags being
ambiguous with negative ASN1 Integers, so I've adjusted the test
to use CONTEXT_SPECIFIC instead with the same tag number (8224).
