License and Attribution of the Solidity Logo?

Hello, Solidity Team,

I am the author of the @localizethedocs organization, which focuses on manufacturing l10n projects for documentation of open-source projects. For example:

- [cmake-docs-l10n](https://github.com/localizethedocs/cmake-docs-l10n),
- [conan-docs-l10n](https://github.com/localizethedocs/conan-docs-l10n),
- [ros2-docs-l10n](https://github.com/localizethedocs/ros2-docs-l10n),
- [and more](https://projects.localizethedocs.org/).

Currently, the [solidity-docs-l10n](https://github.com/localizethedocs/localizethedocs.github.io/issues/213) project is in the incubation phase. To place the Solidity logo at the top of the README, I need to upload the logo to the [static](https://github.com/localizethedocs/static) repository and then access them via jsDelivr. I found the logo SVG files here:

- https://github.com/argotorg/solidity/blob/11be2f4881d1644f15b026d1022388f06a034a34/docs/_static/img/logo.svg
- https://github.com/argotorg/solidity/blob/11be2f4881d1644f15b026d1022388f06a034a34/docs/_static/img/logo-dark.svg

However, I would like to confirm the *license* of this logo and what *attribution* is required.

Based on the [Solidity Brand Guide](https://docs.soliditylang.org/en/latest/brand-guide.html) and the [Wikimedia](https://commons.wikimedia.org/wiki/File:Solidity_logo.svg), how about the following attribution?

Code:

```html

Preview:

Review docs/_static/img/logo.svg and docs/_static/img/logo-dark.svg alongside the Solidity Brand Guide and Wikimedia entry. Confirm the logo license and required attribution for the proposed README use; done means the project provides an authoritative answer or corrected attribution guidance.
