update parser to 2.1.47

[wing328]

PR checklist

• Read the contribution guidelines.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Summary by cubic

Updates io.swagger.parser.v3:swagger-parser from 2.1.46 to 2.1.47 to pick up bug fixes and spec compliance improvements. The generator now uses 2.1.47, which may change parsing and validation outcomes in edge cases.

• Only change: update swagger-parser.version in the root pom.xml.
• Required: regenerate samples and docs; review diffs for parsing-driven changes (e.g., ref resolution, nullable, oneOf/allOf). Adjust tests if outputs change.

^{Written for commit d34c6d8. Summary will update on new commits.}
