Update dockerhub image for Apptainer 1.3

[dmilkie]

I'm trying to use Apptainer 1.3 so I can use build arguments in my Apptainer build.

However, the latest docker image released on DockerHub is 1.2.

I tried building docker image with the command here:
https://github.com/kaczmarj/apptainer-in-docker?tab=readme-ov-file#build-image

but I'm getting this error:

--------------------

  24 | >>>     && ./mconfig $MCONFIG_OPTIONS -p /usr/local/apptainer \
  25 | >>>     && cd builddir \
  26 | >>>     && make \
  27 | >>>     && make install
  28 |

can you try updating the Dockerfile base image to

FROM golang:1.23.2-alpine3.20

[dmilkie]

Yes. that works. I changed to alphine3.20 in line 29 as well
