fix(ci): disable jobs failing due to missing Node.js 20

The actions/download-artifact action is failing with the following
message:

    /__e/node20/bin/node: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by /__e/node20/bin/node)

The problem is that GitHub Actions is dropping Node.js 16 support [1],
and their Node.js 20 binary is too new for our Ubuntu 18.04 Docker
images.

Work around this issue by disabling the failing jobs. They are
non-essential.
