Fixes default Dockerfile user/workdir behavior

[mishushakov]

Fixes issue #1032

---

Note

Preserve Dockerfile USER/WORKDIR when provided and only apply E2B defaults if absent, with tests and CLI fixtures updated accordingly.

• Dockerfile parsing (SDKs):
  • JS (packages/js-sdk/src/template/dockerfileParser.ts): Track USER/WORKDIR usage and only set E2B defaults (user, /home/user) if not specified; keep Docker defaults (root, /) initially.
  • Python (packages/python-sdk/e2b/template/dockerfile_parser.py): Same behavior—preserve explicit USER/WORKDIR, fallback to defaults only when absent.
• Tests:
  • JS: Add tests for default vs. custom USER/WORKDIR in fromMethods.test.ts.
  • Python (async/sync): Add analogous tests in test_from_methods.py.
• CLI template fixtures:
  • Update expected outputs to remove redundant .set_user('user')/.set_workdir('/home/user') when already specified; minor ordering tweak for .setStartCmd in TS fixture.
• Changeset:
  • Minor version bumps for @e2b/python-sdk and e2b; note: keep Docker WORKDIR and USER if specified.
