Provide completion for array elements

Is your enhancement related to a problem? Please describe.

When a schema is defining that the top-level element is an array, there is no completion proposed initially. it seemed like the schema is not recognized.
When an element has array as child, and that completion was not used previously, the user has no ompletion provided and cannot know that an array is expected (so that a - must be inserted). So in fact, it is not only for top-lebvel arrays but for all arrays.

Describe the solution you would like

provide completion for an "Array", so basically a -.
if possible, or maybe for a second iteration, provide all sub-elements but preceded by a -

For instance Camel Yaml DSL,

# yaml-language-server: $schema=https://raw.githubusercontent.com/apache/camel/main/dsl/camel-yaml-dsl/camel-yaml-dsl/src/generated/resources/camel-yaml-dsl.json

completion on new line should propose - or in a second iteration: - beans, - from , - rest and more.

Describe alternatives you have considered

Additional context

The issue names no implementation files or tests; start by locating the schema-driven completion entry point for array-valued nodes and the existing completion tests. Done means a new line under an array schema offers -; nested item completion is described as a possible second iteration.
