feat(config): test for supported id prefix BM-1462 (#3590)

### Motivation

Our recent release failed to publish our packages to NPM. We have since
implemented support for NPM [trusted publishing] to resolve this.
However, we need a minor change to force our packages to publish again.

[trusted publishing]: https://docs.npmjs.com/trusted-publishers

### Modifications

- **packages/config/**

  - **src/config/\_\_test\_\_/`config.test.ts`**

- Added a test case to verify parsing fails for `BaseConfig` objects
with an unsupported `id` prefix.

### Verification

All tests succeed at the root-level by way of the `npm run test`
command.
