fix: simplify CustomAccordion item type casting in VotesDetails once ui-components-library is updated

[coderabbitai]

Context

In web/src/pages/Cases/CaseDetails/Voting/VotesDetails/index.tsx, the CustomAccordion component from @kleros/ui-components-library declares two AccordionItem types. TypeScript resolves to the narrower type, causing type errors when passing accordionItems directly to StyledAccordion.

As a workaround, the following cast was introduced:

<StyledAccordion items={accordionItems as unknown as CustomAccordionItem[]} />

The CustomAccordionItem type alias was also added with an explanatory comment:

//Current ui-components-library version declares two AccordionItem types.
//TypeScript resolves to the narrower type, so we get type errors here.
//Updating to the latest version of the library should allows to simplify this.
type CustomAccordionItem = React.ComponentProps<typeof CustomAccordion>["items"][number];

Action Required

Once @kleros/ui-components-library is updated:

1. Check if the duplicate AccordionItem type issue has been resolved.
2. If resolved, simplify the type cast — remove the CustomAccordionItem alias and pass accordionItems directly.
3. If the issue is still not resolved after the library update, it must be fixed in the library itself as soon as possible.
