devcontainer.yml is useless

[oech3]

devcontainer.yml is useless since

• It does not catch errors by restricted syscalls by seccomp
• Runs on Ubuntu 24.04 which is same with ubuntu-latest runner

Currently, we cannot catch regression for #8474 which depends on newer glibc.
So I suggest one of a

• updating to Ubuntu to 26.04 until ubuntu-latest was updated
• switch to some roling-release distribution
• drop the CI

@martinkunkel2 what do you think ? :)

Update about 1st suggestion: GitHub provides ubuntu-26.04 now. I still want to use some roling-release distribution which has newer glibc more than 26.04 on this CI.

I think we can disable the build/test execution of uutils inside devcontainer for now. I will check the comments above and think about glibc.

Still I think it would be good to keep the CI job that checks if the container itself can be built and started. It provides an easy to setup environment for e.g. new contributors.

We can rename it to devcontainer.yml.example instead of removing, and recover it with glibc newer than GitHub runner later.
