organizationsOrganizationSlugPaymentsGet can not take accept 'application/json'

[RehArk]

Description

HelloAsso PHP SDK: The method organizationsOrganizationSlugPaymentsGet currently forces the Accept header to text/csv.
This prevents retrieving payments in JSON format while using query parameters like pageIndex and pageSize for pagination.

Expected Behavior

• I should be able to call organizationsOrganizationSlugPaymentsGet and get a JSON response.
• Pagination parameters (pageIndex, pageSize) should work with JSON output.

Current Behavior

• The SDK generates the Accept: text/csv header by default.
• Attempting to force JSON by changing the header locally works, but it requires modifying the SDK code.
• The current implementation makes it impossible to get paginated JSON responses without editing generated files.

Steps to Reproduce

$apiInstance = new \OpenAPI\Client\Api\PaiementsApi();
$payments = $apiInstance->organizationsOrganizationSlugPaymentsGet(
    'organizationSlug',
    '2026-01-01T00:00:00+00:00',
    '2026-12-31T23:59:59+00:00',
    null,
    1,
    20,
    null,
    ['Authorized'],
    'Desc',
    'Date',
    false
);
