Missing HSQL create scripts in 7.1.0

[bgiaccio]

Describe the bug
I switched from flowable 7.0.0 to 7.1.0 and ran my unit test which uses HSQL and Autowires org.flowable.engine.RuntimeService via one of my classes, it fails with

Caused by: org.flowable.common.engine.api.FlowableException: resource 'org/flowable/app/db/create/flowable.hsql.create.app.sql' is not available

Expected behavior
org.flowable.engine.RuntimeService should be able to instantiate when connecting to HSQL

Work around
I was able to work around by copying

• https://github.com/flowable/flowable-engine/blob/main/modules/flowable-app-engine/src/main/resources/org/flowable/app/db/create/flowable.h2.create.app.sql
• https://github.com/flowable/flowable-engine/blob/main/modules/flowable-dmn-engine/src/main/resources/org/flowable/dmn/db/create/flowable.h2.create.dmn.sql
• https://github.com/flowable/flowable-engine/blob/main/modules/flowable-event-registry/src/main/resources/org/flowable/eventregistry/db/create/flowable.h2.create.eventregistry.sql

To src/test/resources and rename them with hsql vice h2, meaning I wound up with

• org/flowable/app/db/create/flowable.hsql.create.app.sql
• org/flowable/eventregistry/db/create/flowable.hsql.create.eventregistry.sql
• org/flowable/dmn/db/create/flowable.hsql.create.dmn.sql

Then the test passed

thanks for the feedback, we indeed didn't include hsql in the changes done for 7.1.0. We'll take care of this for the next minor release.
