Add support for map_index in /clearTaskInstances

[sharpnife]

Description

Enhance the /clearTaskInstances REST API endpoint by adding support for clearing specific task instances using map_indexes.

This feature is especially valuable for dynamically mapped operators, which can generate multiple task instances for a single operator. Currently, while the Airflow UI allows clearing individual task instances by map_index, this capability is not available via the /clearTaskInstances endpoint

Use case/motivation

We want to provide users with the ability to retry specific instances of a failed mapped task. To enable this, the REST API should support clearing specific map_index(es) for a given task ID.
