Incorrectly escaped characters in Azure Cloud Shell when connecting to PostgreSQL database

Hello,

I deployed a new Azure Database for PostgreSQL server and database. When I try to connect to the database using the `Connect` button in the `Databases` blade, the default bash command that Azure Cloud Shell tries fails every time.

**Default**: **bold** chars below need to be removed from the command.
```
psql "host=.postgres.database.azure.com port=5432 dbname= user=@ password=\'\$\(az account get-access-token --resource-type oss-rdbms --output tsv --query accessToken\)\' sslmode=require"
```

**Should be:**
```
psql "host=.postgres.database.azure.com port=5432 dbname= user=@ password=$(az account get-access-token --resource-type oss-rdbms --output tsv --query accessToken) sslmode=require"
```
