fix: skip redundant_optional_initialization for @Parameter variables …

[chetan-kmr-0607]

…(#5884)

This change updates ImplicitOptionalInitializationRule so that variables annotated with @Parameter (from TipKit) are ignored when checking for redundant nil initializers. TipKit's @Parameter macro requires explicitly initializing optional parameters to nil; otherwise the macro fails to expand. Without this change, the implicit_optional_initialization rule incorrectly flags these initializers, forcing developers to disable the rule.

Resolves #5884.
