Bump Terrafom version from 1.3.10 to 1.5.7

Version 1.5.7 is the last version before the License change from Mozilla Public License, version 2.0 to Business Source License 1.1

Looks like all checks have passed except conventonalcommits.org has stalled, i couldn't manually retrigger it but found that editing the PR title could retrigger it. All checks are now green.

Non-blocking comment: Issue #1265 was asking for a version with security support, which only comes with 1.7 or 1.8, so I'm not sure that these changes fully address the feature request. I don't fully understand the implications of the license change that occurred after 1.5.7, but assuming we are unwilling to use versions with the new license then this fix an explanation in text is sufficient.

Are there plans to support newer versions of Terraform? We are concerned that using these blueprints presents a risk when we must use newer versions for bug fixes.

Hi @ofek - You can use a newer version of Terraform (just needs to be consistent), the documentation on how to set can be found here: https://github.com/terraform-google-modules/terraform-example-foundation/blob/main/0-bootstrap/README-GitHub.md#requirements

Hey there Andrew, thanks! Yes I saw that but was curious if newer versions are actually tested here. Also I'm not completely familiar with the licensing implications; is the decision that documentation will always reference 1.5.7?

I'll defer to the repo maintainers on the roadmap question, however given the Terraform version compatibility I would not expect issues using more recent v1 Terraform releases. As an example I believe this repo's linter is currently using Terraform v1.9.x.
