Logo licensing for Wikipedia?

[Matthias84]

Hi, I like to enrich the wikidata item with the logo. Unfortunatly there is no license and authorship on the logotype.svg.
Can you clearify if it's copyleft and if the project as a whole is a good author line?

see: https://github.com/ExpressLRS/ExpressLRS-Hardware/tree/master/img/logo for attributions for the logo, I am not knowledgeable enough in copyright law to answer the rest of your question
