Description

The JSON Schema Test Suite is installed from dev-main, and two of its PRs merged today added cases that the validator does not handle yet. CI now fails on every branch (e.g. #994) with 7 failures:

• test(multipleOf): add very small divisor and large integer cases json-schema-org/JSON-Schema-Test-Suite#1254 added "multipleOf with integers above 2^53: 1e20 is not multiple of 3" to optional/bignum.json (divisibleBy in Draft 3). PHP decodes 1e20 as a float, and the float remainder is zero, so the instance is reported as valid. Fails for Draft 3, 4, 6, 7 and 2019-09.
• test(relative-json-pointer): add escaped and special-character json-pointer cases json-schema-org/JSON-Schema-Test-Suite#1253 added "multiple unescaped tildes in the json-pointer part" (0/~~) to optional/format/relative-json-pointer.json. Fails for Draft 7 and 2019-09.

This PR adds the 7 cases to the skip list next to the existing bignum and relative-json-pointer skips. Both files are optional, and the skip list already holds related cases from them.
