Potential ArgumentOutOfRangeException during deployment to Fabric SQL DB

- SqlPackage or DacFx Version: 170.1.61
- .NET Framework (Windows-only) or .NET Core: .NET 8
- Environment (local platform and source/target platforms): Fabric SQL DB

**Steps to Reproduce:**

1. Create table with a few columns and an index in a project, deploy to Fabric SQL DB
2. Remove the last column from the table in source project, deploy again

**Did this occur in prior versions? If not - which version(s) did it work in?**

(DacFx/SqlPackage/SSMS/Azure Data Studio)

Reproduce the two-step deployment against Fabric SQL DB using DacFx 170.1.61, then start at TableAnalyzer.ValidateIndexDependenciesChange in the stack trace and trace the failing index relationship lookup. Done means removing the final table column no longer causes ArgumentOutOfRangeException during deployment.
