Jira Black - Dark Mode

Jira Black is a small extension to transform your JIRA in a nice dark Theme. No fancy stuff, no weird permissions, no tracker : it does what's it's supposed to and that's it! ⚠️ Important Notice: 1 - It's only working on Jira Cloud and not on self hosted Jira (links like https://*.atlassian.net/ ). 2 - It's not working on Confluence. 3 - Thanks to the community who corrected a few glitches and bugs: you guys are awesome! ℹ️ Last update: Excluded Confluence as the CSS is inverted.
