`customUIColors.schema.json` untrusted warning

After the fix in #633, the schema URL was changed to raw.githubusercontent.com, which is supposed to be trusted by default in VS Code. However, I'm still seeing the following warning in my default profile's settings.json:

Unable to load schema from 'https://raw.githubusercontent.com/catppuccin/vscode/catppuccin-vsc-v3.19.0/packages/catppuccin-vsc/schemas/customUIColors.schema.json': Location https://raw.githubusercontent.com/catppuccin/vscode/catppuccin-vsc-v3.19.0/packages/catppuccin-vsc/schemas/customUIColors.schema.json is untrusted.

The warning appears both in an empty window and in a trusted workspace. The warning does not appear in other profiles — only in the default one.

Environment:

• Extension version: 3.19.0
• VS Code version: 1.124.2
• OS: Windows 11
