Unclonable registry repository on Windows

[abstractionfactory]

Currently, the registry repository contains paths that are not valid paths on Windows. This means that it is not possible to work with the registry on Windows:

D:\OpenTofu\registry> git checkout main
error: invalid path 'modules/m/maze2022/s3-webapp./aws.json'
error: invalid path 'modules/o/oragithub/vpc./aws.json'

However, these modules are valid module names in OpenTofu, meaning that people can use them this way. We have three ways forward to fix this:

1. Tighten the requirements for module names and exclude these two module names.
2. Make it explicit that working with the registry dataset on Windows is not supported.

Neither of these is a good option, but I believe it would be important to ensure a wide compatibility for working with the registry data set. We could also ask the two authors if they would like to rename the repo or if they would be ok with having these modules removed from the registry.

Modules in question:

• https://github.com/Maze2022/terraform-aws-s3-webapp.
• https://github.com/oragithub/terraform-aws-vpc.

Update: I believe we can remove these modules safely:

module "test" {
  source = "maze2022/s3-webapp./aws"
  version = "1.0.0"
}

$ tofu init

Note that these module can still be used by directly referencing their Git repositories in the module source because this bypasses the registry.
