Capitalize attribute properties instead of uppercase

[javabster]

fixes #194

I didn't test locally as we don't have any classes that use the @dataclasses.dataclass decorator yet, but I validated the changes using the inspect tool on https://qiskit.org/documentation/stable/0.41/stubs/qiskit.algorithms.optimizers.OptimizerState.html

I opted to just force those specific properties that live under the Attributes section to be capitalized., instead of removing the uppercase setting at the higher level, as that uppercase setting is used for the main CLASS header at the top of the page.

switched to use none instead of capitalise. I couldn't find much info on recommendations for using none vs unset vs initial in CSS so I just opted for none so we don't potentially get screwed over by some unintentional css inheritance
