[BUG]: cannot unmarshal object into Go struct field Protection.lock_branch of type bool after upgrade to v5.13.0

[TheQueenIsDead]

Version

$ terraform version
Terraform v1.3.7
on linux_amd64
+ provider registry.terraform.io/integrations/github v5.13.0

Expected Behaviour

With Terraform config that could successfully execute a plan using module version v5.12.0.
I expect to be able to successfully execute a plan when upgrading to v5.13.0.

Actual Behaviour

I receive an error unmarshalling an existing branch protection

│ Error: json: cannot unmarshal object into Go struct field Protection.lock_branch of type bool
│ 
│   with module.repository["<repo_name>"].github_branch_protection_v3.branch_protection[0],
│   on .terraform/modules/repository/main.tf line 240, in resource "github_branch_protection_v3" "branch_protection":
│  240: resource "github_branch_protection_v3" "branch_protection" {
│ 

Diagnosis

As alluded to in this comment, the module has recently updated go-github from 48.1.0 to 48.2.0 (#1425).

I'm assuming that the SDK adding support for the lock_branch property from the API response (added here), is causing the unmarshalling to fail, and this could perhaps be fixed by adding a lock_branch property to the branch protection state

As @kfcampbell mentioned, this is resolved for me in the 5.14.0 release due to:

google/go-github#2612, fixed in google/go-github#2606, released here, and added to the project as part of #1473.
