If I had to guess it's your logs_url which appears to be a security risk, it's not a good idea to use file:/// URLs and I wonder if the webhook is filtering that out (that's just a guess). Try replacing it with an https:// URL. See my example here

If you want to prove or disprove the point you can try with hardcoded values first, before string formatting.

from ms_teams_webhook_operator import MSTeamsWebhookOperator
def on_failure(context):
    dag_id = context['dag_run'].dag_id
    task_id = context['task_instance'].task_id
    context['task_instance'].xcom_push(key=dag_id, value=True)
    logs_url = "https://example.com"
    teams_notification = MSTeamsWebhookOperator(
        task_id="msteams_notify_failure",
        trigger_rule="all_done",
        message = "**Hello from Airflow!**",
        subtitle = "My subtitle",
        button_text="View log",
        button_url=logs_url,
        theme_color="FF0000",
        http_conn_id="msteams-webhook-url")
    teams_notification.execute(context)
    print('Error Notification is sent to your MS Team Channel')
