as of today, VSCode stopped supporting Glibc 2.26, which means VSCode no longer supports devcontainers with Amazon Linux 2022.
for most other language communities, this is a nonevent, as almost everyone using languages that are not called swift should have upgraded to Amazon Linux 2023 long ago.
this doesn’t actually build an Amazon Linux 2023 toolchain, it just installs an Amazon Linux 2 toolchain on an Amazon Linux 2023 host.
