Fix linting in @huggingface/inference (remove unused vars) (#1348)

Fixes failing lint CI:
```
packages/inference lint:check: /home/runner/work/huggingface.js/huggingface.js/packages/inference/src/tasks/nlp/tokenClassification.ts
packages/inference lint:check:   5:10  error  'toArray' is defined but never used  @typescript-eslint/no-unused-vars
packages/inference lint:check: /home/runner/work/huggingface.js/huggingface.js/packages/inference/src/tasks/nlp/zeroShotClassification.ts
packages/inference lint:check:   5:10  error  'toArray' is defined but never used  @typescript-eslint/no-unused-vars
packages/inference lint:check: ✖ 2 problems (2 errors, 0 warnings)
packages/inference lint:check: Failed
```

From #1315 (cc
@hanouticelina for viz). Strange that in that PR, the CI didn't catch it
(the last
[commit](21f9d34)
was marked as ✅). May need to investigate (cc @coyotte508)
