Description

New Issue Checklist

Feature or Enhancement Proposal

I implemented my own preferred_modifier_order and I wanted to specify the order for isolated and nonisolated keywords, but I didn't find that they were available in the current implementation or documentation, and I didn't find any open issues.

I think a parameter like isolation would be a welcome addition for fine-tuning the modifier order.

Contributor guide

Research direction
Review the current modifier order rule configuration in Source/SwiftLintBuiltInRules/Rules/RuleConfigurations/ModifierOrderConfiguration.swift to understand how existing parameters like `preferred modifier order` are implemented. Then add a new `isolation` parameter that allows users to specify the order of 'isolated' and 'nonisolated' keywords. Update documentation at https://realm.github.io/SwiftLint/modifier order.html and add tests for the new parameter.
