We have a liquibase command that looks something like this:

```sh
/liquibase/liquibase \
       --driver=org.postgresql.Driver \
       --changeLogFile="db.changelog-master.xml" \
       --url=<redacted> \
       --username=<redacted> \
       --password=<redacted> \
       update \
       -Dcoreschema="${core_schema}"
```

After upgrading the CLI from 4.3.3 to 4.4.0, it fails with the following error:

```
Unexpected argument(s): -Dcoreschema=public

For detailed help, try 'liquibase --help' or 'liquibase <command-name> --help'
```

Since the release notes state "this release should be 100% backwards compatible", I expect this is an oversight? Or is there a replacement for the `-Dproperty=value` syntax? I haven't found one looking through `--help` and the [property substitution docs](https://docs.liquibase.com/concepts/basic/changelog-property-substitution.html) at least.

The syntax can also still be found on https://docs.liquibase.com/tools-integrations/cli/home.html:
