fix(cli,csharp,go,java,python,ruby,rust,typescript): fix local vs remote generation parity (#11413)

* add test remote local script

* Update script to use seed:local

* build generator in test script

* update test file

* make build flag optional

* Initial fix attempts

* Fix java x-fern-sdk-name to match remote gen

* Update versions.yml files

* fix(java,cli): simplify local vs remote generation parity fixes

- Add fallback SDK name generation in Java generator when no explicit maven config
- Fix self-hosted GitHub URI format in CLI (owner/repo -> https://github.com/owner/repo)
- Revert TypeScript constructNpmPackage to preserve npm shorthand format
- Remove complex fallback registry config logic from getGeneratorConfig.ts

The Java generator now generates a default maven coordinate (com.<org>.fern:<api>-sdk)
matching Fiddle's RegistryConfigFactory behavior when neither generatorConfig.publish
nor ir.publishConfig provides one.

* fix(cli,seed): improve remote vs local generation parity

- Add shouldGeneratePublishWorkflow flag for npm publish info in local generation
  to match Fiddle's behavior (fixes ts-sdk CI publish job discrepancy)
- Add token: "OIDC" to ts-sdk test config to enable publish workflow generation
- Update JAVA_SDK_MAVEN_COORDINATE to match Fiddle's format (com.<org>.fern:<api>-sdk)
- Remove duplicate getRepoUrlFromUrl call in AbstractGeneratorCli.ts that was
  causing URL mangling for self-hosted GitHub configurations
