When defining URI variables using Link without an explicit schema, OpenAPI generated path parameters defaulted to generic string types and lost format information (such as UUID/ULID or integer types) from the target property metadata.

This PR infers primitive schema type and format in LinkFactory from the linked property when none is explicitly configured on the Link.

Functional Test

tests/Functional/OpenApiLinkSchemaTest.php

public function testLinkSchemaIsInferredFromLinkedProperty(): void
{
    $response = self::createClient()->request('GET', '/docs', [
        'headers' => ['Accept' => 'application/vnd.openapi+json'],
    ]);
    $this->assertResponseIsSuccessful();

    $json = $response->toArray();
    $parameters = $json['paths']['/link_schema_parents/{parentId}/children/{id}']['get']['parameters'];

    $parentParam = $parameters[0];
    $this->assertSame('path', $parentParam['in']);
    $this->assertTrue($parentParam['required']);
    $this->assertSame(['type' => 'string', 'format' => 'uuid'], $parentParam['schema']);

    $idParam = $parameters[1];
    $this->assertSame('path', $idParam['in']);
    $this->assertTrue($idParam['required']);
    $this->assertSame(['type' => 'integer'], $idParam['schema']);
}

Thanks for the PR this looks like a new feature, I need to check what the consequences are on the openapi / hydra specs. Can you target main ?

I figured it was a bugfix, as Im not adding a new functionality to the framework, and am changing the incorrect parameter type in the generated spec to the correct type.

But I can ofcourse target main if preferred 👍

The correct answer is :no I can't ...
#8677 is the PR targeting main, I can't git/phpstorm ...
