Add yarn preinstall script

What does this MR do and why?

Add yarn preinstall script

Yarn seems to have problems at times, if one uses an <alias>@npm:<name> and those packages are being updated. In case one switches branches the node_modules folder seems to end up being a corrupted somehow. So we add a simple script which forcefully removed node_modules.

How to set up and validate locally

1. yarn install
2. yarn install, nothing should happen
3. Change e.g. the version in package.json from "sentrybrowser": "npm:@sentry/browser@^7.21.1" to "sentrybrowser": "npm:@sentry/browser@^7.66.0"
4. yarn install should print a warning and remove node_modules before install
