SQL truncated at lines starting with "go" in migrationBuilder.Sql

## File a bug
I can still reproduce #32457 in v8.0.6

Example script in `migrationBuilder.Sql`
```
SELECT
ColumnA,
ColumnB,
GoodColumn,
ColumnC
FROM
Table
```

Is truncated before executing to
```
SELECT
ColumnA,
ColumnB,
```
And fails with `Incorrect syntax near ','`

If I change to:
```
SELECT
ColumnA,
ColumnB,
[GoodColumn],
ColumnC
FROM
Table
```

It works. I presume it looks for lines starting with `go`?
