I was playing around with a version of install_blender.sh that could work with Blender 3.0 (based on some changes I made here: #411). It looked roughly similar to your version, however, I am thinking it would probably be beneficial to be able to utilize the version argument to choose which URL it should pull.

My first thought is that maybe just hard-coding a bunch of version URLs would be ok for now. Thoughts?

Note: additionally, it would be great if the Docker build could utilize the version number as an argument to make it easier to test different versions quickly. Something like the following:

ARG BLENDER_VERSION=2.81
ENV BLENDER_VERSION=${BLENDER_VERSION}

RUN env | grep BLENDER

$ docker build -t exporter:test .
...
Step 4/4 : RUN env | grep BLENDER
 ---> Running in ba8bdf34ca5f
BLENDER_VERSION=2.81
...

$ docker build --build-arg BLENDER_VERSION=2.91 -t exporter:test .
...
Step 4/4 : RUN env | grep BLENDER
 ---> Running in e83b6425efcf
BLENDER_VERSION=2.91
...

Is there interest in pulling this to Blender 4.0? I was thinking it might be worthy. Looking for support.
