[Vuejs]-TypeScript's type inference for Promise.all fails in Vue on WebStorm2023.1

this will be fixed in WebStorm 2023.2, you can try this in the EAP version that is generally available right now.
Here’s a link to the related announcement https://blog.jetbrains.com/webstorm/2023/05/webstorm-2023-2-eap2/

I also personally tested it in the latest EAP Version and it seems to work in my opinion.
