Add kdeconnect integration (Alternative version)

[freundTech]

Proposed change

This commit adds icons and logos for the new KDE Connect integration I developed.

I already made another PR (#3233) using the KDE Connect icon, where @frenck mentioned that he would expect the KDE logo to be used for this integration. I layed down in a comment (https://github.com/home-assistant/brands/pull/3233#issuecomment-1060611493) why I think that the KDE Connect logo, instead of the KDE logo would be the right choice.

However, to speed up review I decided to create this alternative PR with the KDE Logo, so the team can decide which one to merge.

Type of change

• [x] Add a new logo or icon for a new core integration
• [ ] Add a missing icon or logo for an existing core integration
• [ ] Add a new logo or icon for a custom integration (custom component)
  • [ ] I've opened up a PR for my custom integration on the Home Assistant Python wheels repository
• [ ] Replace an existing icon or logo with a higher quality version
• [ ] Removing an icon or logo
