Replace Rocker-based images with posit for the `ghcr.io/geocompx/minimal` image

[Robinlovelace]

This will reduce image sizes.

I've just tested

docker pull posit/r-base:4.5-noble
docker pull posit/r-base:4.5-bookworm

And both work great. Not sure if there are slim versions: adding -slim fails. Any thoughts welcome, thanks @e-kotov for flagging issues with the previous version of this issue (it was garbage)!

AI hallucinations, apologies. I did a load of reading on it and asked for them to be summarised but seems to have failed. Will update the links.

Would be nice though if Posit had their own flavour of data-sci container images with Positron.

They need devcontainers to work first, that way you just set

  "image": "posit/r-base:4.5-noble"

E.g.: https://github.com/itsleeds/tds/blob/cc961cd8ac215c8ff313c8aa4728876a045dc65c/.devcontainer/devcontainer.json#L4

Docs from posit: https://solutions.posit.co/envs-pkgs/environments/docker/ but that seems out of date mentioning rstudio/ instead of posit/ images.

rstudio/r-docker#134 and rstudio/r-docker#135 are relevant here.
