Specify origin when checking out stable's .gitattributes (#8586)
Specify origin when checking out stable's .gitattributes (#8586)

The problem is that when you have a fresh clone (and you're not doing a hotfix) the "branch" variable in `scripts/release` points to `origin/develop`. There is no notion of a local stable branch. So commands like the one this PR changes need to specify a remote.

Closes #8585.
