Description:

Duplicate detector entries were introduced in this PR: #4261
Hence, we were getting the following warnings:

2025-07-30T12:09:22+05:00	info-0	trufflehog	possible duplicate detector configured	{"detector": "StripePaymentIntent"}
2025-07-30T12:09:22+05:00	info-0	trufflehog	possible duplicate detector configured	{"detector": "BitbucketAppPassword"}
2025-07-30T12:09:22+05:00	info-0	trufflehog	possible duplicate detector configured	{"detector": "Hasura"}

This PR addresses the issue by:

• Removing the duplicate entries from the engine defaults file
• Alphabetically sorting the newly added Tableau detector within the list
