Add information about update-ability, default value, & validation

### Terraform CLI and terraform-plugin-docs Versions

latest

### Use Cases or Problem Statement

It would be nice for users to know more about a parameters behaviors without having to write lengthy custom descriptions. It would also be nice to be able to have a unified look to documentation so common questions are answered uniformly and generated instead of hand typed.

Specifically it would be nice to know a parameters:
- default value - if applicable
- updateability - if it can be updated or requires replacement
- validators - what types of validations are run against the input

### Proposal

Technical implementation is currently limited by missing fields in the [schema](https://github.com/hashicorp/terraform/issues/35646). That aside, here are some proposals for how to display the information:

```markdown
- `my_parameter`:
- Type:
- Default: "one"
- Plan Modifiers:
- Forces Recreation
- Validators:
- Any one of: `one`, `two`, `three`
```
