VSCode Markdown Code blocks Terraform Syntax highlighting

This extension adds Terraform syntax highlighting to Markdown fenced code blocks.

Code blocks like the following:

```tf
terraform {
  required_version = "1.1.2"
}

provider "aws" {
  region = var.aws_default_region
}
```

will be highlighted, like:

Setup

This extension does not add the grammar; it only connects Markdown ASM code blocks to the existing ASM grammar.

For this reason, it requires a preexisting extension that provides the grammar, for example, Terraform.
