Devcontainer multiple postCreateCommands

[FelixBenning]

Currently the only way to execute multiple postCreateCommands is by using "&&". Since this command is suggested to be used to install additional tools like git, curl, etc. this can get quite long. For example the RTools Extension requires a .NET installation. So if I want a linter for python and R I have to do something like this:

"apt-get update && apt-get install -y git && conda install --name conda_env pylint -y && wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb && dpkg -i packages-microsoft-prod.deb && apt-get update && apt-get install -y aspnetcore-runtime-3.1"

And since JSON does not do line wrapping this is absolutely unreadable.

postCreateCommand runs in the workspace folder, you could, e.g., place a script in the .devcontainer folder and invoke it as ./.devcontainer/postCreateCommand.sh.
