Closes #347

I got the icons directly from Atlassian's logo library and just tinkered them to the repo's standards

Here's a poor preview of each:

Hi there,

I'm Devicons' Peek Bot and I just peeked at the icons that you wanted to add using icomoon.io.
Here is the result below (top left):

Here are the zoomed-in screenshots of the added icons:

Note: If the images don't show up, it's probably because it has been autodeleted by Imgur after 6 months due to our API choice.

The maintainers will now take a look at it and decide whether to merge your PR.

Thank you for contributing to Devicon! I hope everything works out and your icons are accepted into the repo.

Cheers,
Peek Bot 😊

However, when the bot removes the color, the icon became the rectangle that you saw in the bot's result:

Icomoon also reports that it found the color white in the icon:

Can you try removing the white fill and recommit?

Can you try removing the white fill and recommit?

There was a shady invisible path layer hiding 🐱‍👤, I think I've dealt with it now.
