Hey, this PR adds/changes the following

  • Updated challenges to the new manifest (021530e)
  • Adds the package archival services for debian and ubuntu images (8b4c712, 1026b29)
  • Removed all alpine based images (35eb948), instanced templates (0d3eb8f) and kernel-PWN (41a03eb)
  • Added preparsing for sagemath (56c544b)
  • Added file extensions (6e02f00)
  • Added templates for docker-compose.yml files (e13ac2a)
  • Changed templates to use the flag placed in the environment (aff947a, 8978a0a)
  • Added a new template for creating offline-challenges with dynamic flags (33a6f2c)

There are unfortunately a lot of changes in this PR.
We could also split it up into multiple PRs in order to make it easier to review.

Ported all debian and ubuntu based images to use the archival services.
In addition, all containers were switched from the docker-hashes to
timestamped images to give challenge authors a better feeling of how
old/new the image is.
I updated the pwn debian 12.11 template to debian 12.12.
Since the minor version changed, I renamed the folder do not include it.

Since this change might spark some discussion, this is a seperate commit
All minor versions have been updated, the table listing the versions in
the readme-md has been updated and .version has been updated.
This Commit adds file-extensions for files that are not binaries (e.g.
python or bash-files).
This was done because file-extensions are present for other challenges
aswell (e.g. the solidity or php template).

This closes #4
I accidentay removed too much in
ecd71ba, this commit adds it back in
This PR adds tempaltes for docker-compose-files that can be included in
the dist.
We are currently missing support from the makefile.
I had a copy-paste error in the manifest for the connection info.
removed old flag.txt, added new entrypoint to write the flag into a file
and start nsjail.
In all non-jail templates, all references to flag.txt have been removed
in the challenge subdirectory and the flag is being read from the
environment
Added a tempalte that dynamically gegerates challenge dists

The manifest for offline-dynamic-python is still wrong, I'll fix that in the afternoon.
