snake_case_param_names in a filter and order while API expects CameCase

If entities are using camel case names, then api-platform expects get requests with filters like /?yourCamelCaseFieldValue=somevalue&order[anotherCamelCaseFieldValue]=ASC.

But in the code there no conversion.

`case GET_LIST: {
const {
pagination: {page, perPage},
sort: {field, order},
} = params;

if (order) collectionUrl.searchParams.set('order[${field}]', order);
if (page) collectionUrl.searchParams.set('page', page);
if (perPage) collectionUrl.searchParams.set('perPage', perPage);
if (params.filter) {
Object.keys(params.filter).forEach(key => {
const filterValue = params.filter[key];
if (!isPlainObject(filterValue)) {
collectionUrl.searchParams.set(key, params.filter[key]);
return;
}

Object.keys(filterValue).forEach(subKey => {
collectionUrl.searchParams.set(
'${key}[${subKey}]',
filterValue[subKey],
);
});
});
}`
