asdf logo?

### Is your feature request related to a problem? Please describe

I love using asdf, but icon themes for text editors do not contain icons for `.tool-versions` file.

### Describe the proposed solution

Does asdf have its own logo?

If yes, I could make icons based on it and create pull requests in the repository with icon themes

### Describe similar `asdf` features and why they are not sufficient

### Describe other workarounds you've considered

Start with the issue body and its 35-comment discussion, since no repository file or test is identified. Determine the agreed direction for an official asdf logo or asset guidance; done means the requester can use that decision to prepare icon-theme pull requests.
