feat(upload): add documentation for new setting

[Tyki]

What does it do?

This pull request add a new settings to limit the concurrency of uploads to 1 in the media library.

It also fix a small issue when the file size is checked only after that images optimizations are applied. But it means that, whatever the image size is, sharp will try to optimize it. On low ram environments, it leads to OOM.

How to test it?

Add the new setting in the configuration for the upload plugin: limitConcurrentUpload

  upload: {
    config: {
      limitConcurrentUploads: true
    }
  },

and then try to upload multiple assets in the same time

Thank you, @Tyki!
The PR is approved, but I'll wait for the corresponding strapi/strapi PR to be merged before merging the present PR (hence the flag: merge pending release—it will make some test fail to ensure it's not merged prematurely)
