Jack Ling 095c69c424 fix(cmd/gf): fix gf env and gf build --dumpEnv command error (#4635) ...

## Summary
- Fix `gf env` and `gf build --dumpEnv` command failing when `go env`
outputs warning messages
- When `go env` outputs warnings (e.g., invalid characters in
environment variables), it returns non-zero exit code but still provides
valid output
- The original code would fail in this case

## Changes
- Only fail when `go env` returns empty output, allow non-zero exit code
with valid output
- Skip lines that don't match `key=value` format instead of failing with
Fatal error
- Add debug log for skipped lines to help troubleshooting
- Add unit tests for env command

## Related Issue
Fixes #4469

## Test plan
- [x] `gf env` command works correctly even when `go env` outputs
warnings
- [x] `gf build --dumpEnv` works correctly
- [x] Added unit tests pass
