Fixes #16701

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

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

  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*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master (upcoming 7.1.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

I've fixed the spring maven plugin tests with #16720 instead.

closing this one.

@wing328 just a sidenote: would have preferred you to merge this one first (so i get the credits in the commit history) or told me right away in #16701 (comment) that you were going to overhaul this (so i could have saved myself the time to update this PR for nothing).

[wing328]

your commits already included in my PR: https://github.com/OpenAPITools/openapi-generator/pull/16720/commits, so you do get the credits. You can run git log in the latest master to verify.

have a nice weekend.

@wing328 Sincerest apologies for what could have been considered a slight rant from my side. I missed the fact you kindly built upon my earlier commits, thanks a lot. 🙏

Keep up the great work, wishing you an awesome start into the week.
