python 3.12 on Amazon Linux 2023

Question

I'm trying to build a container to run on ECS with Amazon Linux 2023 as the base image.  I'd like to use Python 3.12 to run an application on the container, and I'm having a hard time getting the package manager (`dnf`) to find Python 3.12.

The line...
```
RUN dnf -y install python3.12
```
...in my dockerfile fails with the following error:
```
0.605 No match for argument: python3.12                                                                                                                                                                                                  
0.614 Error: Unable to find a match: python3.12   
```
How do I install Python 3.12 on Amazon Linux 2023 using `dnf`?

Why not try installing Python3.12 using pyenv as shown below?  
```
FROM amazonlinux:2023

RUN dnf install -y git tar gcc \
                   zlib-devel bzip2-devel readline-devel \
                   sqlite sqlite-devel openssl-devel \
                   tk-devel libffi-devel xz-devel

RUN curl https://pyenv.run | bash && \
    echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc && \
    echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc && \
    echo 'eval "$(pyenv init -)"' >> ~/.bashrc && \
    source ~/.bashrc && \
    pyenv install 3.12.4 && \
    pyenv global 3.12.4
```

Looks like python3.11 is the latest available in the repos.

```bash
dnf list | grep python3
```
