Stream-Analytics Transformation Update doesn't accept multiline query/SAQL

### Describe the bug

We are updating stream analytics transformation using "az stream-analytics transformation update"
We have multiline query like
```
WITH {TABLENAME} AS (SELECT * FROM {INPUT NAME} TIMESTAMP BY Date)

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT1} FROM {TABLENAME}

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT2} FROM {TABLENAME}

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT3} FROM {TABLENAME}
```

Tried different format like
```
@"
WITH {TABLENAME} AS (SELECT * FROM {INPUT NAME} TIMESTAMP BY Date)

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT1} FROM {TABLENAME}

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT2} FROM {TABLENAME}

-- some comment
SELECT {column1}, {column2}, {column3} INTO {OUTPUT3} FROM {TABLENAME}
"@
```

And
```
{line1} `n{line2} `n{line3}
```

Still no success.

Used fiddler to check api request payload. Only first line of the query is sent. Remaining lines are ignored.
