Subject: [PATCH] fix: Remove trailing comma in CREATE TABLE tenant_model SQL
 (#15832) (#15836)

### What problem does this PR solve?
The last column definition `INDEX idx_instance_id (instance_id),` in the
`CREATE TABLE tenant_model` statement has a trailing comma, which causes
a MySQL syntax error during deployment.

Closes #15832

### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)

### How was this tested?
- [x] Visual inspection: the trailing comma on line 837 has been removed
