Subject: [PATCH 18/24] feat(SolidLintRule): add parameter parsing refactor:
 use Map<String, Object?> instead of LintOptions as the enabled field is
 implicitly true for all rules that the analyzer processes remove RuleConfig
 as it is no longer needed

-//     Work (including but not limited to damages for loss of goodwill,
-//     work stoppage, computer failure or malfunction, or any and all
-//     other commercial damages or losses), even if such Contributor
-//     has been advised of the possibility of such damages.
-
-//  9. Accepting Warranty or Additional Liability. While redistributing
