Render BCMath\Number (PHP 8.4+) as string instead of object

Before

{
    "@context": "/contexts/MathNumber",
    "@id": "/math_numbers/1",
    "@type": "MathNumber",
    "id": 1,
    "value": {
        "@id": "/.well-known/genid/d884d3a7bec8d1a52024",
        "@type": "Number",
        "scale": 2,
        "value": "300.55"
    }
}

After

{
    "@context": "/contexts/MathNumber",
    "@id": "/math_numbers/1",
    "@type": "MathNumber",
    "id": 1,
    "value": "300.55"
}

The symfony/serializer:7.3 added the NumberNormalizer, the symfony/framework-bundle:7.3 registered it.

In CI and the job PHPUnit (PHP 8.4), api-platform install symfony/framework-bundle:7.2

  - Locking symfony/framework-bundle (7.2.x-dev 42ac8bb)
  - Locking symfony/http-client (v7.3.6)
  - Locking symfony/http-client-contracts (v3.6.0)

if I try locally

composer require --dev "symfony/framework-bundle:7.3" -W --dry-run 

....
- symfony/object-mapper is locked to version 7.4.x-dev and an update of this package was not requested.
- symfony/framework-bundle v7.3.0 conflicts with symfony/object-mapper >=7.4.
