text: Title: [DOC] FCNClassifier publication reference is incorrect
  Body: #### Describe the issue linked to the documentation
  
  The [FCNClassifier](https://www.sktime.net/en/latest/api_reference/auto_generated/sktime.classification.deep_learning.FCNClassifier.html) references the work of Zhao et al. 2017 [1], while it is actually an implementation of Wang et al. 2017 [2]. Also see the [underlying implementation](https://github.com/hfawaz/dl-4-tsc/blob/master/classifiers/fcn.py).
