Update example in Vector article (#10100)

* Update vector-search-transact-sql.md

I think there is a mistake in Example 2, line 158:
te `SIMILAR_TO` value should refer to a column:
```
        SIMILAR_TO = t.v, 
```
Instead of variable:
```
        SIMILAR_TO = @QV, 
```

* Update vector-search-transact-sql.md

Fix mistake referencing to the wrong table alias
