Scan JS Package: Remove Build

[nateweller]

To ensure compatibility with __() and @wordpress/i18n, the scan package needs to be built by consumers such as the Jetpack and Jetpack Protect plugins.

Proposed changes:

• Removes references to a "build" directory from the package.json file, opting to provide the TS source code directly to consumers.
• Removes use of jetpack:src from exports, since default is now the same ./src/index.ts value.

Other information:

• Have you written new tests for your changes, if applicable?
• Have you checked the E2E test CI results, and verified that your changes do not break them?
• Have you tested your changes on WordPress.com, if applicable (if so, you'll see a generated comment below with a script to run)?

As mentioned at peb6dq-3as-p2#comment-2024, this isn't really a good reason to do this. But there are other reasons you might decide to make the package TS-only (at least for now), and this PR is good to do that.
