Parsing of OpenTofu/Terraform files containing provider defined functions fails

[matthias-bruhse]

Describe the issue Checkov fails to parse .tf files if they contain provider defined functions, introduced in OpenTofu 1.7 and Terraform 1.8. Both OpenTofu and Terraform use the double colon notation, which causes the fail.

Examples

  provider::provider_name::function_name()
