- [X] I have read the [Contributing Guidelines on issues](https://github.com/facebook/docusaurus/blob/main/CONTRIBUTING.md#issues).

### Description

In order to create a more cohesive and visually appealing online presence, I propose the inclusion of custom logo icons for the following platforms associated with our project:
1.Discord
2.Stack Overflow
3.GitHub
4.Twitter
As marked in screenshot below.


### Has this been requested on Canny?

No

### Motivation

By incorporating distinctive icons for each platform, we can not only enhance the aesthetic appeal of our repository but also provide a quick and recognizable visual representation for users navigating our project across different platforms.
I understand the importance of maintaining a professional and consistent brand image, and I am willing to collaborate on the design or provide suitable options for your consideration. If you have any specific design guidelines or preferences, please feel free to share them.

### API design

I believe that these custom icons will contribute positively to our project's overall user experience and branding.



### Have you tried building it?

No

### Self-service

- [ ] I'd be willing to contribute this feature to Docusaurus myself.
