ECONNRESET when building MFE images with multiple parallel stages

[mariajgrimaldi]

Description

Currently, to avoid connection errors while building MFE images, we must use a custom build kit configuration file to restrict the number of parallel stages. See these posts for more info on the errors: https://discuss.openedx.org/t/npm-err-code-err-socket-timeout-when-building-mfe-image/10414, overhangio/tutor-mfe#55 (comment). The root cause is still unknown.

How to reproduce

You can try building a new image without the Prepare docker if building MFE step. You'll get a similar error to:
