Include user metadata in the first insert for objects

[anmolsood21]

In order to be able to use passed in user metadata for INSERT RLS policies, the user metadata should be included in the first insert request. Currently, the first insert request doesn't have any user metadata set.

See https://discord.com/channels/839993398554656828/1338777324845404262/1338777324845404262 for more context

Cant see whats behind the discord link but think I might be running into this issue as well.

        const { error } = await supabase.storage
          .from(uploadUrlData.bucket)
          .uploadToSignedUrl(uploadUrlData.path, uploadUrlData.token, file, {
            upsert: true,
            metadata: uploadUrlData.metadata
          });

Results in the file being uploaded, and an object. However, none of the metadata i've set is actually set in the table. Not in the metadata or user_metadata column
