bnd-maven-plugin -plugin can't work with multiple plugins

When context aware configurations are created as java interface, the **bnd-maven-plugin** is not able to scan the class, hence no context aware configurations are detected.
https://github.com/adobe/aem-project-archetype/blob/d02bbda3853a5168c6b95406bb914a544246dbf8/src/main/archetype/pom.xml#L237

### Expected Behaviour
java interface context aware configurations must be detected

### Actual Behaviour
java interface context aware configurations are not detected hence classes are not available in the bundle.

### Reproduce Scenario (including but not limited to)

#### Steps to Reproduce
1. Create a project using archtype
2. Create java interface for context aware configurations e.g. https://sling.apache.org/documentation/bundles/context-aware-configuration/context-aware-configuration.html#describe-configurations-via-annotation-classes-1
3. deploy the project and check configuration, there is a Context-Aware Configuration web console at https://:/system/console/slingcaconfig, which allows querying context-aware configurations in the repository and viewing their properties. e.g. https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/developing/configurations.html?lang=en#context-aware-web-console

#### Platform and Version
AEMaaCS

#### Fix
Add multiple plugins as comma separated values i.e. https://bnd.bndtools.org/instructions/plugin.html
example
`-plugin org.apache.sling.caconfig.bndplugin.ConfigurationClassScannerPlugin,org.apache.sling.bnd.models.ModelsScannerPlugin`

#### Sample Code that illustrates the problem
N/A
#### Logs taken while reproducing problem
N/A

Start in src/main/archetype/pom.xml around line 237 and inspect the bnd-maven-plugin configuration. Reproduce with a generated project containing a Java interface for a context-aware configuration, then verify that both scanner plugins are configured and the interface is detected in the bundle.
