Add new openapi-normalizer rule: ADD_UNSIGNED_TO_INTEGER_WITH_INVALID_MAX_VALUE

when set to true, auto fix integer with maximum value 4294967295 (2^32-1) or long with 18446744073709551615 (2^64-1) by adding x-unsigned to the schema

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/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.
• In case you are adding a new generator, run the following additional script :

  ./bin/utils/ensure-up-to-date.sh
  

  Commit all changed files.
• File the PR against the correct branch: master (6.3.0) (minor release - breaking changes with fallbacks), 7.0.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.

The code checks specifically for (2^32)-1 and (2^64)-1. But there could be cases when the schema limits the value to a smaller maximum that should also be handled as uint and ulong. Will the current code change handle these cases?

But there could be cases

When these use cases emerge, we can adjust the rules accordingly (which means this rule may subject to breaking changes in the future)
