Swift highlighting: parameter labels and argument labels are captured as property

[ollieatkinson]

Zed’s Swift tree-sitter highlights currently classify Swift labels as property, so themes cannot distinguish them from real member properties.

func printSummary(for jobs: [BuildJob]) -> Int
//                ^^^ external parameter label should not be property

Current behaviour:

• External/internal function parameter names can be captured as property.
• User config cannot cleanly fix this without also changing the highlighting of real properties.

Expected:

• Parameter names should probably be variable.parameter.
• Argument labels should probably be label, variable.parameter, or another non-property capture.
• Real properties like jobs.count, job.id should remain property.

Potential fix area (need help):

(parameter external_name: (simple_identifier) @variable.parameter)
(parameter name: (simple_identifier) @variable.parameter)
(value_argument name: (value_argument_label) @label)
