Hydra documentation returning with double @context (docs.jsonld)

[durimjusaj]

API Platform version(s) affected: 4.1.16

Description
Just updated to v4.1.16, and docs.jsonld is now returning a result with two @context entries.

Possible Solution
ApiPlatform\JsonLd\HydraContext - has already @context key in array

ApiPlatform\Hydra\Serializer\DocumentationNormalizer

• computeDoc: line 556 - Adds a new @context entry to the documentation.
• getContext: line 580 - Returns HYDRA_CONTEXT merged with another array that already contains @context

An array merge would do the trick.

return array_merge(HYDRA_CONTEXT['@context'] ?? [],
[
    '@vocab' => $this->urlGenerator->generate('api_doc', ['_format' => self::FORMAT], UrlGeneratorInterface::ABS_URL) . '#',
