[oliver194]

This will add golang versions: 1.18, 1.19, 1.20, 1.21, 1.22 and Python 3.12.

• Also added missing python 3.11 to readme and fixed node.js 20 link

not opposed at all, but perhaps we should consider releasing a python 3.x image, and a go 1.x image?

(provided those two behave well with the semver doctrine... my personal experience with python at least is that stuff (python libraries) does in fact break between minor releases)

As part of the ptero-eggs merge in, we now have all the recent golang versions, and a go_latest tag for the most recent golang version. We can easily add a go_1 or similar tag. With the new CI workflow they are basically free tags.

We can do the same with the python images
