fix(types): remove PromiseConstructor augmentation to respect ES lib settings

Remove the `Promise.withResolvers` and `Promise.try` type augmentations from
`@types/bun`. These methods are now part of TypeScript's standard libraries:
- `Promise.withResolvers` is in ES2024 (`lib.es2024.promise.d.ts`)
- `Promise.try` is in ESNext (`lib.esnext.promise.d.ts`)

By removing these ambient augmentations, projects can now properly validate
their ES compatibility. For example, a project targeting ES2022 will correctly
receive a TypeScript error when using `Promise.withResolvers`, and TypeScript
will suggest upgrading to ES2024.

Fixes #25974
