fix: evalation-context import, remove deprecation, add types import to…

[kyle-ssg]

• added evaluation-context.ts to bundle since it is imported in types.d.ts
• Removes missed deprecation
• Adds types to package.json imports to allow for backwards compatibility, without this we get

import { IFlags, IRetrieveInfo, LoadingState } from 'flagsmith/types';
TS2307: Cannot find module flagsmith/types or its corresponding type declarations.

by using this we can remove the types export from these files:

• flagsmith-js-client/react.d.ts

  Line 3 in ad4a206

  export * from './types';

• flagsmith-js-client/index.d.ts

  Line 4 in ad4a206

  export * from './types';

I believe they'd serve different purposes to be honest.

The code I added preserves the ability to import from flagsmith/types, without this it was a breaking change.

The code you added (which is preferred but new) allows us to import types directly from flagsmith.
