Add a solution to "Too many file open" error

Adding a solution to the "Error: Too many files open (OS error 24)". Suggested only Docker-related solution, as there seem to be various ways, and those might be googled easily.

@timvisee Good idea! I wanted to avoid writing an article like https://woshub.com/too-many-open-files-error-linux/, but that's a pretty straightforward way

Makes sense! Setting using ulimit is simple, but only sets it for that session. The article you linked shows a few good ways to make this limit persistent. But I guess the users can figure that out themselves.
