Discuss how to create packages from templates

[kenji-miyake]

Currently, Autoware.Auto uses autoware_auto_create_pkg for this.
https://gitlab.com/autowarefoundation/autoware.auto/AutowareAuto/-/blob/1111bb025ced60a5399719f079e81933690a7183/src/tools/autoware_auto_create_pkg/package.xml

However, I think it can be replaced by other ways like this because:

• Few people use ros2 run autoware_auto_create_pkg command.
• It can easily check the build warnings/errors of template files.
• It can be used for not only template packages but also template repositories including CI workflows.

It isn't necessary so far, but I'll leave it as it is for a while.
