Thanks for this, could you sign the commit. After that I can merge and build a release a new patch version of the provider to the terraform registry

@kitagry with the increased threat of supply chain attacks I've set the added a requirement that all commits to master be signed; it's overkill in this case but I believe creating a culture where work can be traced cryoptographically to contributors benefits both users and developers. I'd like to accept these changes but they need to be signed first. Otherwise in 7 days I'll create a separate commit that's signed by me with this change and credit you as a co-author in the commit log - however this'll mean your fork will diverge and would need reconciling before you can commit any changes upstream to this repo; so it'd be best to avoid if possible

The links below have walkthroughs of how to do it, otherwise feel free to contact me via the email on my profile if you want any help
