New Issue Checklist

Issue Description

addMetadata and addTag do not work in Cloud Code with Parse FS Adapter.

Steps to reproduce

I used the below code but the createdById and groupName values were not saved

Parse.Cloud.beforeSaveFile(async (req) => {
    const {file, user} = req;
    file.addMetadata('createdById', user.id);
    file.addTag('groupName', groupName);
});

Actual Outcome

The value createdById and groupName were not saved in ParsFile. Actually in ParsFile, metadata and tags are not saved.

Expected Outcome

When file.metadata() and file.tags() are called, the values createdById and groupName should respectively be returned

Environment

Server

• Parse Server version: 5.2.7
• Operating system: Ubuntu
• Local or remote host: etc

Database

• System (MongoDB or Postgres): MongoDB
• Database version: 5.0.10
• Local or remote host: etc

Logs

None

Start by reproducing the issue with Parse.Cloud.beforeSaveFile using the shown addMetadata and addTag calls, Parse Server 5.2.7, and the Parse FS Adapter. Check whether file.metadata() and file.tags() return the values after saving, then trace the adapter's file-storage handling. Done means metadata and tags persist and are returned by those methods.
