Subject: [PATCH 1/2] fix: use `isolatedModules: true` in tsconfig.json

This setting ensures the module can be used in projects where the workflow
includes type checking and transpilation as two separate steps.

See: https://ncjamieson.com/dont-export-const-enums/

Fixes: https://github.com/cloudevents/sdk-javascript/issues/456
