oasdiff v1.32.1: fixes the hang on cyclic schemas
Every action now runs oasdiff v1.32.1, which fixes the v1.32.0 hang on specs whose schemas reference each other in cycles (oasdiff #1252). A workflow on such a spec no longer runs until the job times out. Recursive schemas are handled as in v1.31.0 again, so the circularRef field of diff json/yaml output is back and the non-determinism of oasdiff #1230 is back until the next release; everything else from v1.32.0 is kept.
No changes to the actions themselves. oasdiff/oasdiff-action/*@v0 now points at this release.
