tsc throws an error as it can't find `@react-leaflet/core/lib/context` when `"module": "preserve"` is set in `tsconfig.json`

[40thieves]

Bug report in v4

I'm running tsc with the preserve value for the module setting in tsconfig.json on a project with React Leaflet.

• [x] All peer dependencies are installed: React, ReactDOM and Leaflet.
• [x] Using the latest version of React and ReactDOM v18.
• [x] Using the supported version of Leaflet (v1.8.0 minimum) and its corresponding CSS file is loaded.
• [x] Using the latest v4 version of React-Leaflet.
• [x] The issue has not already been reported.
• [x] Make sure you have followed the quick start guide for Leaflet.
• [x] Make sure you have fully read the documentation and that you understand the limitations.

Expected behavior

No tsc errors are found.

Actual behavior

tsc throws the following errors:

Steps to reproduce

I've made a minimal repro: https://github.com/40thieves/ts-react-leaflet which installs the relevant dependencies and configures tsconfig.json with the module: preserve setting. To reproduce, you need to:

1. Clone & npm install
2. Run npm run check

(apologies, I'm not sure StackBlitz would work as it's related to running tsc)
