add sync openapi version workflow

[alexfreska]

• Shared workflow for syncing version in openapi spec file(s) with the repo's latest release version, the workflow checks if the version needs to be bumped and if so opens a PR.
• Includes support for repos with multiple spec files, but assumes we want then all synced to the same general release version.
