Manage NullPointerException when namespaceFiles.enabled property is not true

[bellec1u]

What changes are being made and why?

Manage the case when the property namespaceFiles.enabled is not true.

The objective of this pull request is to be able to not commit the namespace files to a git repository.

Note

This case can be reached by using false as value.

So maybe the main issue seems coming from the @PluginProperty annotation as lombok set it at null ?
Why not using native boolean ?

Moreover, I'm not able to exclude them via namespaceFiles.exclude

Example:

- id: test
  type: io.kestra.plugin.get.Push
  namespaceFiles:
    enabled: false
  ...

Execution result:

java.long.NullPointerException: Cannot invoke "java.lang.Boolean.booleanValue()" because the return value of "io.kestra.core.models.tasks.NamespaceFiles.getEnabled()" is null
