Simplify options of bar graph interactive component (remove nesting)

[#47632253]

Previosuly options of the bar graph were inside "options" property.
Remove this unnecessary nesting to make bar graph definition more
similar to line graph. Also some option names are changed (e.g.
minVale to min, maxValue to max).
Update interactive JSONs to use new, simpler bar graph definition
