.DS_Store files are not ignored by git

Describe the solution you'd like

Add the line

.DS_Store

to the .gitignore file in the project generated by rsgem

Given this is a file exclusive to macOS (system dependent) I'd rather nudge macOS users to add .DS_Store to their global ~/.gitignore file, don't you think?

Yes, it makes sense but there's a catch.
I usually use /bin/bash a Docker container for some development tasks.
The Docker container usually has a git client of its own.
I try not to use git from the Docker container but sometimes I inadvertently do it.
Using a git config local to the project works out of the box for me even in those cases

I guess it'd be better for the dockerfile to include the default .gitignore for the user. Otherwise we would be adding some OS-specific noise to rsgem IMHO. Closing it for now.
