Add team_name tags to Amazon executor metrics

[justinpakzad]

Description:

This PR adds team_name as a tag on the task adoption duration metrics for Amazon executors in multi-team deployments.

Metrics that now include team_name:

• batch_executor.adopt_task_instances.duration
• ecs_executor.adopt_task_instances.duration
• lambda_executor.adopt_task_instances.duration

When there is no team (global executors, or older Airflow versions without multi-team support) the tag is omitted (prune_dict) and the metric behaves exactly as it does today.

Tests:

Added a parametrized test for each executor that checks the timer is called with the team name tag when a team is set, and with no tag when it is not. The tests are guarded with the AIRFLOW_V_3_1_PLUS constant for compatibility.
