RN and Node 14+ is missing package.json in "export" field in package.json

[ospfranco]

Issue Description

Expected Behavior

TypeORM should work just fine with RN and Node 14+ (since Node12 will eventually be retired)

Actual Behavior

Since Node 14+ all files that are meant to be accessed from third-parties need to be declared in the package.json "export" field. Current configuration is mostly fine, but React Native also reads the package.json. Since this field is not specified the react native packager is not able to link the package and it fails the import on runtime.

You can see a more detailed issue here:

react-native-community/cli#1168

I've locally fixed the issue in my node_modules by changing:

"./package.json": "./package.json", // <-- added this line on typeorm package.json exports field
"./*.js": "./*.js",

Steps to Reproduce

1. On any react-native project using a node 14+ version trying installing typeorm
2. try running the app, there will be a package.json.js file not found:

warn Package typeorm has been ignored because it contains invalid configuration. Reason: Cannot find module '/Users/osp/Developer/quick-sqlite/example/node_modules/typeorm/package.json.js'
