fix: Show @deprecated descriptions

[Jiralite]

@deprecated descriptions were being ignored. Only the @deprecated tag would show on the website. This pull request reveals the descriptions of this tag in a warn-like format.

Before

```JavaScript /** * Emitted when an interaction is created. * @event Client#interaction * @param {Interaction} interaction The interaction which was created * @deprecated Use {@link Client#interactionCreate} instead */ ```  ```JavaScript /** * Emitted whenever a message is created. * @event Client#message * @param {Message} message The created message * @deprecated Use {@link Client#messageCreate} instead */ ```  ```JavaScript /** * The type of this embed, either: * * `rich` - a generic embed rendered from embed attributes * * `image` - an image embed * * `video` - a video embed * * `gifv` - an animated gif image embed rendered as a video embed * * `article` - an article embed * * `link` - a link embed * @type {string} * @see {@link https://discord.com/developers/docs/resources/channel#embed-object-embed-types} * @deprecated */ ```  ```JavaScript /** * Whether the channel is editable by the client user * @type {boolean} * @readonly * @deprecated Use {@link VoiceChannel#manageable} instead */ ``` 

After

```JavaScript /** * Emitted when an interaction is created. * @event Client#interaction * @param {Interaction} interaction The interaction which was created * @deprecated Use {@link Client#interactionCreate} instead */ ```  ```JavaScript /** * Emitted whenever a message is created. * @event Client#message * @param {Message} message The created message * @deprecated Use {@link Client#messageCreate} instead */ ```  ```JavaScript /** * The type of this embed, either: * * `rich` - a generic embed rendered from embed attributes * * `image` - an image embed * * `video` - a video embed * * `gifv` - an animated gif image embed rendered as a video embed * * `article` - an article embed * * `link` - a link embed * @type {string} * @see {@link https://discord.com/developers/docs/resources/channel#embed-object-embed-types} * @deprecated */ ```  ```JavaScript /** * Whether the channel is editable by the client user * @type {boolean} * @readonly * @deprecated Use {@link VoiceChannel#manageable} instead */ ```

I'd love if it would have some marging top and bottom so it's not so contained or squished with the description of the method itself.

I believe I've made suitable adjustments, @iCrawl!
