Bug Report: wrong elixir version installed in cimg/elixir v1.16.x and v1.17.x

Describe the bug

All cimg/elixir images tagged with patch versions of 1.16 and 1.17 contain the wrong elixir version (patch .0 instead of what is tagged):

images tagged with 1.16.1, 1.16.2, 1.16.3 contain elixir version 1.16.0
images tagged with 1.17.1, 1.17.2 contain elixir version 1.17.0

It seems that the elixir version was never updated when these images were published.

Images tagged with 1.15.8 are still correct, they contain elixir version 1.15.8.

Tested with -erlang-26.2.1 images.

To Reproduce

Minimal sample project that reproduces the issue: https://github.com/Kittysplit/cimg_test The build results on commits show which tag versions are correct and which aren't: https://github.com/Kittysplit/cimg_test/commits/main/

Sample config:

version: 2.1

workflows:
  check:
    jobs:
      - compile

jobs:
  compile:
    docker:
      - image: cimg/elixir:1.17.2-erlang-26.2.1
    steps:
      - checkout
      - run:
          name: "Check elixir version"
          command: elixir --version
      - run:
          name: "Install hex"
          command: mix local.hex --force
      - run:
          name: "Install rebar"
          command: mix local.rebar --force
      - run:
          name: "Get elixir dependencies"
          command: mix deps.get
      - run:
          name: "Build elixir"
          command: mix compile --warnings-as-errors
      - run:
          name: "Run elixir tests"
          command: mix test

The elixir --version step output already shows that it's running the wrong elixir version:

Erlang/OTP 26 [erts-14.2.1] [source] [64-bit] [smp:36:8] [ds:36:8:10] [async-threads:1] [jit:ns]

Elixir 1.17.0 (compiled with Erlang/OTP 26)

If it contains an elixir project and the elixir version is fixed including patch version (with elixir: "~> 1.17.2"), mix compile / mix test will fail with ** (Mix) You're trying to run :cimg_test on Elixir v1.17.0 but it has declared in its mix.exs file it supports only Elixir ~> 1.17.2. See sample project linked above to reproduce.

Expected behavior

Images should contain the tagged elixir version, or higher patch version for images tagged with only a minor release (as described in https://github.com/CircleCI-Public/cimg-elixir?tab=readme-ov-file#tagging-scheme)

Workarounds

Only use images tagged with minor version (eg. 1.17, not 1.17.1/1.17.2)
Set elixir version without patch version in elixir: "~> 1.17", however this still doesn't use the tagged patch version.
