### Terraform Version ```shell v1.10.4. I confirmed the issue is present in 1.10.0, but not in 1.9.8. ``` ### Terraform Configuration Files N/A ### Debug Output N/A ### Expected Behavior ``` $ terraform -v Terraform v1.9.8 on linux_amd64 $ terraform console > yamldecode("foo: 10_000_000") { "foo" = 10000000 } ``` I expect the number with underscores defined in the YAML to be interpreted as a number. This has been a part of the [YAML spec](https://yaml.org/type/int.html) since YAML v1.1. ### Actual Behavior ``` $ terraform -v Terraform v1.10.4 on linux_amd64 $ terraform console > yamldecode("foo: 10_000_000") { "foo" = "10_000_000" } ``` On terraform v1.10.0 and later, the value is being incorrectly parsed as a string. ### Steps to Reproduce Use any sample YAML that includes a number with underscores. ### Additional Context I searched through open and closed issues but couldn't find anything reporting this. I apologize if it's a dupe! ### References _No response_ ### Generative AI / LLM assisted development? _No response_
