Update dependencies including map abstraction and multi-types in kin-openapi

[dependabot[bot]]

Update dependencies. This PR uses the latest version of kin-openapi which changed schema/type from a single string to an array. After this PR oasdiff will support schema/type as follows:

• Specs with multiple types are allowed as input
• Diff fully supports multiple types
• Breaking-changes, changelog and "flatten allOf" are backward compatible, meaning that they generate the same output for schemas with a single type
• Breaking-changes, changelog and "flatten allOf" are not yet tested for schemas with multiple types (tracked by https://github.com/Tufin/oasdiff/issues/534 and https://github.com/Tufin/oasdiff/issues/535)
