* 🐛bug fix: enable to use the new format of OpenAI's project API Key (#328)

* fix(config.ts): remove validation for OCO_OPENAI_API_KEY length to accommodate variable key lengths

* build

* ♻️ refactor(config.ts): Addition of UnitTest environment and unittest for commands/config.ts#getConfig (#330)

* feat(jest.config.ts): update jest preset for TS ESM support and ignore patterns
feat(package.json): add test:unit script with NODE_OPTIONS for ESM
refactor(src/commands/config.ts): improve dotenv usage with dynamic paths
feat(src/commands/config.ts): allow custom config and env paths in getConfig
refactor(src/commands/config.ts): streamline environment variable access

feat(test/unit): add unit tests for config handling and utility functions

- Implement unit tests for `getConfig` function to ensure correct behavior
  in various scenarios including default values, global config, and local
  env file precedence.
- Add utility function `prepareFile` for creating temporary files during
  tests, facilitating testing of file-based configurations.

* feat(e2e.yml): add unit-test job to GitHub Actions for running unit tests on pull requests

* ci(test.yml): add GitHub Actions workflow for unit and e2e tests on pull requests

* refactor(config.ts): streamline environment variable access using process.env directly
test(config.test.ts): add setup and teardown for environment variables in tests to ensure test isolation

* feat(package.json): add `test:all` script to run all tests in Docker
refactor(package.json): consolidate Docker build steps into `test:docker-build` script for DRY principle
fix(package.json): ensure `test:unit:docker` and `test:e2e:docker` scripts use the same Docker image and remove container after run
chore(test/Dockerfile): remove default CMD to allow dynamic test script execution in Docker

* refactor(config.test.ts): anonymize API keys in tests for better security practices

* feat(config.test.ts): add tests for OCO_ANTHROPIC_API_KEY configuration

* refactor(config.ts): streamline path imports and remove unused DotenvParseOutput

- Simplify path module imports by removing default import and using named imports for `pathJoin` and `pathResolve`.
- Remove unused `DotenvParseOutput` import to clean up the code.

* refactor(config.test.ts): simplify API key mock values for clarity in tests

* test(config.test.ts): remove tests for default config values and redundant cases

- Removed tests that checked for default config values when no config or env files are present, as these scenarios are now handled differently.
- Eliminated tests for empty global config and local env files to streamline testing focus on actual config loading logic.
- Removed test for prioritizing local env over global config due to changes in config loading strategy, simplifying the configuration management.

* new version

+
+This flag can only be used if the `OCO_EMOJI` configuration item is set to `true`. This flag allows users to use all emojis in the GitMoji specification, By default, the GitMoji full specification is set to `false`, which only includes 10 emojis (🐛✨📝🚀✅♻️⬆️🔧🌐💡).
+This is due to limit the number of tokens sent in each request. However, if you would like to use the full GitMoji specification, you can use the `--fgm` flag.
