Update external links in downstream docs to AMQ Streams deployment information

Due to restructuring in the Streams documentation, linked content has been relocated, breaking the following link in the SQL Server and MySQL documentation:

For more information, see link:{LinkStreamsOpenShift}:getting-started-str[{NameDebeziumInstallOpenShift}]

The link is used downstream in the following files:
modules/debezium-using/proc-deploying-debezium-mysql-connectors.adoc:25:
modules/debezium-using/proc-deploying-debezium-sql-server-connectors.adoc:26:

The correct link is:

link:{LinkDeployStreamsOpenShift}[{NameDeployStreamsOpenShift}]

Corrections apply in the following upstream files:

mysql.adoc:L1831
sqlserver.adoc:L1668
