Render asset check description with the Description component (#25765)

## Summary & Motivation

This closes #23829 and makes
the rendering of the `asset_check` description the same as `asset`
description

## How I Tested These Changes

Ran locally with the following definitions file and checked the
description rendering in the asset, asset_check with description, and
asset_check without description:

```
from dagster import Definitions, asset_check, asset

@asset
def my_asset():
    """ A simple asset with a docstring
    
    And some more text

    """
    return None

@asset_check(asset=my_asset)
def my_asset_check():
    """ Asset check for my_asset

    With a docstring

    With some more text
    """
    return None

@asset_check(asset=my_asset)
def my_asset_check2():
    return None

defs = Definitions(
    assets=[my_asset],
    asset_checks=[my_asset_check, my_asset_check2],
)
```

The result in the UI looks like this:
