@nesl247 I updated and added a baseline with less important checks but there are still about 100 errors that we need to take a look at :/

I'll try to work towards this as I can to help out. Thanks for getting it started!

I made https://github.com/api-platform/core/pull/7239 @soyuka @nesl247 if you want to take a look.

Every phpstan errors are fixed or ignore with an identifier. And it will be easier to fix one identifier at a time
