feat(java-spring): operationId is extracted as a constant for Spring Boot api definitions

[Rokko11]

• operationId is extracted as a constant for Spring Boot api definitions - similar to the PATH constant
• Update test expectations

PR checklist

• [x ] Read the contribution guidelines.
• [ x] 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.
• [x ] 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

Extracts operationId into String constants in the java-spring generator and references them from @Operation(operationId=...). This removes repeated string literals and aligns with existing PATH_* constants.

• New Features
  • API interfaces now define OPERATION_<OPERATION_ID> and annotations reference ClassName.OPERATION_<OPERATION_ID>.

^{Written for commit e4c2228. Summary will update on new commits.}

When flag operationIdAsConstant is enabled, the operationId is getting extracted as a constant - similar to the PATH constant

Thanks for the PR. Do we need an option for this or this enhancement should be included for everyone?

With option it would be backward compatible, but if preferred I'll drop the configuration option.

without the option, please elaborate what it breaks
