[BUG]: Pie `legend`, `showlegend` attributes don't accept array values

[camdecoster]

Description

plotly.js 3.3.1 updated the pie trace to allow arrays of boolean values to be passed in for the legend and showlegend attributes. In plotly.py 6.5.1 (the latest version), the BooleanValidator doesn't allow for arrays. As such, arrays can't be passed in for these attributes in plotly.py.

Steps to reproduce

• Install plotly.py 6.5.1
• Run the following code:

  import plotly.graph_objects as go
  
  pie = go.Pie(
      labels=["A", "B", "C"],
      values=[65, 15, 20],
      showlegend=[True, False, False],
  )
  
  fig = go.Figure([pie], go.Layout())
  fig.show()

• Note the ValueError that's raised

Notes

• This is the first time that a boolean attribute has had arrayOk as true in the schema. That's why this update is required.
