Example for this using post-hook seems to be overwritten on load, leaving a confusing replacement

• I have read the contribution docs, and understand what's expected of me.

What page(s) or areas on docs.getdbt.com are affected?

https://docs.getdbt.com/reference/dbt-jinja-functions/this#examples

https://github.com/dbt-labs/docs.getdbt.com/blob/current/website/docs/reference/dbt-jinja-functions/this.md

What changes are you suggesting?

The examples section of the "About this" docs page opens with a paragraph about using grants instead of post-hook without any context as to why it brings this up.

In older versions of dbt, the most common use of post-hook was to execute grant statements, to apply database permissions to models right after creating them. Starting in v1.2, we recommend using the grants resource config instead, in order to automatically apply grants when your dbt model runs.

I figured this was perhaps pasted into the doc in error, so I went to edit the page to remove it, only to find the source includes a perfectly comprehensible example that happens to use a post-hook.

<Snippet src="hooks-to-grants" />

<VersionBlock lastVersion="1.1">

### Grant permissions on a model in a post-hook

<File name='dbt_project.yml'>

```yaml
models:
  project-name:
    +post-hook:
      - "grant select on {{ this }} to db_reader"
```

</File>

</VersionBlock>

I am not sure exactly why/how this snippet is being overwritten when the page is loaded, but the result a bit bewildering. I feel either the example should be displayed as-is or removed from the page. Thanks!
