Fixes #5773: guard against user's `~/.gitconfig` setting `init.templateDir` (#5774)

This is a fix for issue #5773. The approach involves passing an explicit `--template` parameter to the `git init` commands in `dev_tools/bash_scripts_test.py`. This will override any settings that the user happens to have for `init.templateDir` in their `~/.gitconfig` file.
