Docs - product feedback: Gitlab.com provided runners available space in container

Hi, I'm trying to build a relatively simply project which I'm running out of disk space with. (see e.g. this job)

I would like to try and fix that but I cannot find any information on how much space there's provided per runner in the free plan for open sourced projects.

Could you provide information and update the documentation accordingly?

Additionally, are there any statistics on how often that boundary is hit in reality? Due to my personal situation I cannot self-host runners atm so I would really like to use the provided ones.

Thanks in advance and thank you for providing this great service.
