Fix Flyin Plugin VSCode download bug

[Future-Outlier]

Tracking issue

Fixes flyteorg/flyte#4284

Why are the changes needed?

We don't support cases when using default flyin image and we want to install additional extensions.
https://github.com/flyteorg/flytekit/blob/master/plugins/flytekit-flyin/Dockerfile
For example, you use COPILOT_CONFIG, which include python, jupyter and copilot extensions in the list.
The old code will not install the copilot extensions for 2 reasons:

1. permission denied for flytekit user in the container
2. there's a bug in the decorator.py, which will skip downloading additional extensions if code-server is executable in the beginning

How was this patch tested?

unit test and in single binary mode.

Setup process

0. start the flyte single binary mode
1. build an image by Dockerfile
2. print the log in the container and see if the copilot extension is installed or not

docker buildx build --platform=linux/amd64 -t localhost:30000/flyin-0112:1536 -f DockerfileFlyin_v2 .
docker push localhost:30000/flyin-0112:1536
pyflyte run --remote --image localhost:30000/flyin-0112:1536 vscode_task.py wf

# 1. Update the necessary packages for flytekit
# 2. Install code-server
# 3. Download code-server extensions for Python and Jupyter via wget
# 4. Install flytekit and flytekit-flyin with no cache
# 5. Delete apt cache. Reference: https://gist.github.com/marvell/7c812736565928e602c4
# 6. Some packages will create config file under /home by default, so we need to make sure it's writable
# 7. Change the permission of /tmp, so that others can run command on it

now that we have more than one package in this plugin, can we use setuptools find_packages instead of listing them exhaustively here?

[Future-Outlier]

Yes, I can try it!
