[BUG] [Python] Path contains several parameters, only the first parameter is assigned the correct schema

Bug Report Checklist

• Have you provided a full/minimal spec to reproduce the issue?
• Have you validated the input using an OpenAPI validator (example)?
• Have you tested with the latest master to confirm the issue still exists?
• Have you searched for related issues/PRs?
• What's the actual output vs expected output?
• [Optional] Sponsorship to speed up the bug fix or feature request (example)

Description

If path contains several parameters, only the first parameter is assigned the correct schema, the remaining parameters are all assigned the Any type.

If the parameter is an array, this information is lost. In the generated Python client api, the parameters are therefore not declared in the "_collection_formats" variable. Arrays are therefore not serialized properly!

openapi-generator version

Tested with all versions 7.4.0 and higher

Path /apps.
A number of apps should be displayed. Several id filters are available for selection

Steps to reproduce

Related issues/PRs

Suggest a fix

Reproduce the issue with the supplied OpenAPI declaration, Python generator command, and python.yml.proc.yml configuration, then trace how the Python client generator processes the path parameters after the first one. Done means workspace_ids, category_ids, publisher_ids, and similar parameters receive their schemas and array parameters appear in _collection_formats with correct serialization.
