feat: simple-async template as a alternative for simple ✨

[kdheepak]

This PR does the following:

1. Renames existing async template to component
2. Makes simple support ratatui v0.25.0
3. Adds a new simple-async uses tokio to implement an async event stream
   • simple-async is identical to simple except that it uses async events

This will make it easier for someone new to Ratatui to dip their toes into async without understanding the nuances of the now component template.

Looks good to me. Though I'm not sold on component name, I don't really understand what does it involve when choosing this template.

I'm hoping to document why it is called component later. Open to other suggestions too when I improve the docs for it. This template might even go away as we rework the tutorials and build a new template.

To me this seems like a full app template so ... full, app? opinionated was good too.

I'm just putting myself as a user and I don't know what component is supposed to mean, it's fine if it's explained in the doc later though.

[kdheepak]

Yeah, opinionated is good too. What do we think about namespaced templates? qmk has keyboard layouts in their folder that have username prefixes. So this can be in the kdheepak/opinionated and I can add another template that's kdheepak/panic-hooks-and-logging etc.

[Valentin271]

So for our case it could be something like

templates/
├── simple/
└── async/
    ├── simple/
    └── opinionated/

Or are you talking about templates namespaced by user? If so I think this would belong better in each user's repo, potentially with links from here.

[kdheepak]

I think cargo generate gets a little weird with this like of nested folder structures. It's also easier to go to this repo and know that top level folder names are all templates you can get with cargo generate ratatui-org/templates $folder_name.

I was talking about the latter and I like linking to user's repos here.

[Valentin271]

Alright flat folder it it then.

It's also easier to go to this repo and know that top level folder names are all templates

I prefer that too.

We could link to well maintained/interesting templates. Is it a section for this repo or awesome-ratatui though?

[kdheepak]

I think awesome-ratatui but could be convinced otherwise :)

[Valentin271]

Actually we could link the awesome-ratatui template section from here.

Do you know of some templates we could add to initiate the section?
