Subject: feat: Add a parameter to the sync to specify the download/upload page
 (#2408)

This adds a parameter to change the upload/download page size, this
could help if one gets a '413' in a selfhosted scenario.

## Checks
- [x] I am happy for maintainers to push small adjustments to this PR,
to speed up the review cycle
- [x] I have checked that there are no existing pull requests for the
same thing
