Remove springfox from templates

[wing328]

a follow up PR to #23283 and #23280

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 || 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.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• 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

Remove Springfox from all Java Spring and Kotlin Spring templates. Switch to Springdoc (or source docs), drop /v2/api-docs and @ApiIgnore, remove all springfox conditionals/deps, and stop gating Springdoc config by useSwaggerUI (Boot 2 parent now 2.7.15).

• Migration
  • Set documentationProvider=springdoc (or source) in your generator config.
  • Update any /v2/api-docs references to /v3/api-docs.
  • Remove io.springfox:springfox-swagger2; use springdoc-openapi deps. Springdoc core is no longer tied to useSwaggerUI.
  • If you used @ApiIgnore, remove it; use @ParameterObject where applicable.

P2: springdoc-openapi.version is only defined when useSwaggerUI is true, but the springdoc core dependency still uses ${springdoc-openapi.version} when useSwaggerUI is false. Disabling useSwaggerUI will generate a pom.xml with an unresolved property and fail the build.</violation>
