Docker image size is blowing up

When comparing the last few releases in
https://console.cloud.google.com/gcr/images/kaggle-images/GLOBAL/python
it is quite noticeable that recently there has been a sudden increase in the docker image size, e.g. from virtual size 6.2 GB of `v125` to virtual size of 8.3 GB of `v129`, i.e. a 34% increase.

When uncompressed, docker reports that `v125` results in a 19 GB container, while `v129` results in a 23 GB container, i.e. a 21% increase.

I noticed this while running (the heaviest of) my workflows on GitHub Actions, randomly getting errors like
```
System.IO.IOException: No space left on device : '/home/runner/runners/2.302.1/_diag/Worker_20230304-204952-utc.log'
```
While surely the amount of disk space that GitHub offers is not your responsibility, you may still want to check if there is any way to keep the size of the docker image under control, and if possible keep it from growing at this rate any further.

Comece comparando as camadas da imagem Docker e o histórico de build de v125 e v129 usando a imagem vinculada do Google Container Registry. Identifique quais alterações da release explicam o crescimento e, em seguida, verifique se uma imagem subsequente não aumenta mais na taxa relatada, preservando o conteúdo existente da imagem.
