Does not support dev_overrides

$ hcledit version
0.2.9

$ cat ~/.terraformrc

provider_installation {
    dev_overrides {
        "mycompany/provider" = "/Users/me/go/bin/"
    }

    direct {
        exclude = ["mycompany.com/*/*"]
    }
}

$ cat ~/.terraformrc | hcledit block get dev_overrides
failed to parse input: -:3,9-10: Invalid argument name; Argument names must not be quoted.

$ cat ~/.terraformrc | hcledit block list
failed to parse input: -:3,9-10: Invalid argument name; Argument names must not be quoted.

However, the official docs say to quote the attribute name.

Hi @skyzyx, Thank you for reporting the issue!

If I understand correctly, the syntax of .terraformrc is invalid as the HCL2 because an argument name ("mycompany/provider") must not be quoted, as shown in the error message.

The error comes from the HCL2 parser here:
https://github.com/hashicorp/hcl/blob/v2.17.0/hclsyntax/parser.go#L87

I was curious how Terraform parses the .terraformrc and found that the dev_overrides block was decoded as a map object using the low-level HCL1 API.
https://github.com/hashicorp/terraform/blob/v1.5.5/internal/command/cliconfig/provider_installation.go#L230-L244

The HCL1 is the legacy syntax used before Terraform v0.12 that allowed a block to be interpreted as a map depending on the application schema, which is not allowed in HCL2. I don't know why such a legacy one is still used after Terraform v0.12, but I assume it is due to some historical reason or technical constraint.

The hcledit supports only HCL2 and cannot parse invalid files as HCL2.

I didn't realize that Terraform core was falling back to HCL1 to parse this, as this is the current syntax published in the official docs.

Thank you for taking a look.
