UPGRADE NOTES:

- Library used by Terraform (hashicorp/go-getter) for
installing/updating modules was upgraded from v1.7.5 to v1.7.6. This
addresses
[CVE-2024-6257](https://nvd.nist.gov/vuln/detail/CVE-2024-6257). This
change may have a negative effect on performance of `terraform init` or
`terraform get` in case of larger git repositories. Please do file an
issue if you find the performance difference noticable.
([#&#8203;35376](https://togithub.com/hashicorp/terraform/pull/35376))

BUG FIXES:

- `terraform test`: Removed additional erroneous error message when
referencing attributes that don't exist.
([#&#8203;35408](https://togithub.com/hashicorp/terraform/pull/35408))
- `import` blocks: Fix crash that occurs when incorrectly referencing
the `to` resource from the `id` attribute.
