This package is also used by plugins. If a plugin dev updates this will they need to update their tsconfig config and webpack config too?

yes. do plugins typically manage their own dependencies, or do they rely on create-plugin to update them? or some mixture of both? 🤔

either way, we should probably add a CHANGELOG to this repo to explain the changes. it will be something like:

• update tsconfig-grafana as well
• update the build to use new jsx runtime (this step will vary depending on the existing build, e.g. babel, esbuild, etc.)
• run the react codemod on the plugin code

Blocking this as the changes here will force plugins to use auto jsx which right now will bundle jsx-runtime into the plugin. This will cause the plugin to break when loaded in a version of Grafana running React 19. See this comment in the community team React 19 epic for further info.

We will get there but I don't want this creeping in and causing us more bother with the upgrade path for plugins.
