dvc repro: Tuples in parameters are always marked as modified

[janrito]

Bug Report

Description

When tuples are used in parameters, dvc always marks them as modified.

dvc status

outputs

train_model:
  changed deps:
    model/parameters.py:    
      modified: NGRAM_VECTORIZER_RANGE

regardless of whether NGRAM_VECTORIZER_RANGE has been changed

Can reproduce. Taking a look

When serializing the ParamsDependency to the lock file (dvc.lock), the tuple gets converted to a list (because dvc.lock is in YAML format).

On the subsequent dvc repro execution, the value in the params file gets correctly loaded as a tuple but compared against the serialized list (https://github.com/iterative/dvc/blob/main/dvc/dependency/param.py#L127), always reporting it as modified.
