Place containers in yoda-idiomatic spot

[asmacdo]

When I wrote this originally I did:
datalad install -d . ///repronim/containers code/containers

But I should have used -s:
datalad install -d . -s ///repronim/containers code/containers

where is syntax error? there seems to be full refactoring on where to place the containers subdataset... and it should be harmoneous with the way we do in the monolythic script we also have in README and then test on CI.

Please make description proper and ensure consistency

[asmacdo]

the "syntax error" actually never made it into the README, my mistake.

whatever you need to change, change in your step by step version, not here!

I believe that your changes to monolythic version lead to some odd CI fails starting to happen (I didn't analyze)

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding

since daily testing performed just fine: https://github.com/ReproNim/containers/actions/runs/9376864122/job/25817510428

I can only repeat again -- do not change original monolythic version, change your step by step to match in terms of commands!

This works on typhon and CI passes. Doesn't run for me locally, but that is tracked #125 and shouldnt block merge here.
