Hi, we're trying to upgrade our meltano docker image to

meltano/meltano:v3.3-python3.10

and have a plugin that is dependent on

python3.9

while the rest are compatible with

3.10

. I want to structure the dockerfile so that it supports multiple python versions and do

meltano install

of the plugins during different build stages with different python versions. Can someone show me how the dockerfile should be structured or provide an example? https://docs.meltano.com/reference/settings/#python
