Add branding for tomorrow.io by symlinking to climacell

[raman325]

Proposed change

ClimaCell as a company rebranded to Tomorrow.io right around when we introduced the climacell integration 🙃 After consulting some other members, I decided to build a new integration which is more or less a stripped down version of climacell (climacell supported two different APIs, this one only supports the one that's currently supported by the company). I've reached out to the company for updated branding but for now they are using their old logos, so symlinking should suffice

Type of change

• 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

The symlink is created in an incorrect folder (root instead of the integrations folder)
