Query Parameter Serialization should use explode as default

[cbartz]

According to the OpenAPI Specification, the default serialization method for query parameters is style: form and explode: true. Therefore, if these keywords are not given, oazapfts should use the method https://github.com/cellular/oazapfts/blob/992128226bbaa103c4fc93b8b2dec81da953520a/src/runtime/query.ts#L45 for parameter serizaliation. Due to line https://github.com/cellular/oazapfts/blob/992128226bbaa103c4fc93b8b2dec81da953520a/src/codegen/generate.ts#L38 the default method used is form instead.

Example: If the lines https://github.com/cellular/oazapfts/blob/310117038b6a5119c8a121063d9f4d6f36f43b59/demo/petstore.json#L172-L173 are removed, the result should be the same as without removal. Instead, the generated code uses QS.form

export function findPetsByStatus(status: ("available" | "pending" | "sold")[], opts?: Oazapfts.RequestOpts) {
    return oazapfts.fetchJson<{
        status: 200;
        data: Pet[];
    } | {
        status: 400;
        data: string;
    }>(`/pet/findByStatus${QS.query(QS.form({
        status
    }))}`, {
        ...opts
    });

instead of QS.explode

export function findPetsByStatus(status: ("available" | "pending" | "sold")[], opts?: Oazapfts.RequestOpts) {
    return oazapfts.fetchJson<{
        status: 200;
        data: Pet[];
    } | {
        status: 400;
        data: string;
    }>(`/pet/findByStatus${QS.query(QS.explode({
        status
    }))}`, {
        ...opts
    });
}

This behaviour was observed with version 3.5.0 .
