[BugFix] Bar Chart Fixes

[deeleeramone]

1. Why?:

   • Bar charts in Jupyter were always being set as "overlay" every time figure.show() was run.

   • hovertemplate and width were inaccessible from the bar_kwargs entry in the Generic Charts because those values were defined by default.

2. What?:

   • Removes the lines that updated the figure layout as "overlay" when isatty was False.
   • Prioritizes the user-supplied hovertemplate and width in openbb_charting.charts.generic_charts.bar_chart so that multiple values are not sent to the params.

3. Impact:

   • More better.

4. Testing Done:
