Fixed NodeJS 16 install for Almalinux Dockerfile

[dorinelfilip]

The NodeJS 16 package is signed using SHA1, which is deprecated in Almalinux/RHEL 9 [1] and the build fails with an error such as:

19.04 Importing GPG key 0x9B1BE0B4:

  58 |     # Install Node.js v16

I fixed the problem by temporarily allowing SHA1 signatures.

Thanks a lot for the contribution. However, it looks like that node was upgraded to v20, and it is apparently fixed.
