Global gitconfig fails to copy to devcontainer with postCreateCommand

[AvinZarlez]

Related to this issue #98 there still seems to be a problem for the global git config.

My local git config is copied, but my global git config is not. Settings that only existed in my global config like my name and email are not copied.

It seems that a default empty global git config is created when using postCreateCommand. In my case, I am running a script "postCreateCommand": "sh ./scripts/env-setup.sh"

Here is what my containers global git config looks like when using postCreateCommand:

# This is Git's per-user configuration file.
[user]
# Please adapt and uncomment the following lines:
#	name = 
#	email = vscode@b97bec6ca4f1.(none)

If I change it to postAttachCommand, then an exact copy of my actual global git config file from my machine is copied correctly into the dev container.

We could ignore the empty [user] section. As a workaround you can comment out the [user] line as # [user].

I confirmed manually removing the global file ( or commenting out the empty user section ) does make it so the proper global file will be copied. Although that is a manual step that may be annoying/easy to miss/hard to explain to developers when making a fresh container.

I think ignoring an empty [user] section is ideal.
