Problem

grafana-tsconfig does not currently support TypeScript 6. Users who wish to utilize the latest TypeScript features are unable to do so, and this creates friction for projects that want to upgrade.

Solution

Update the grafana-tsconfig package to fully support and be compatible with TypeScript 6. This may include updating dependencies, configuration files, and adding CI checks for TypeScript 6 compatibility.

Alternatives

Remain on an older version of TypeScript or use custom tsconfig overrides, but both approaches reduce alignment and support.

Additional context

Adding support for TypeScript 6 will help keep plugins modern and compatible with the latest TypeScript ecosystem.
