Missing sourcemap warnings

Bug description

Minor issue here - there are some missing sourcemap warnings logged to the console at the start of our test runs:

Sourcemap for "/Users/<user>/<repo>/node_modules/aws-sdk-client-mock-jest/dist/es/jest.js" points to missing source files
Sourcemap for "/Users/<user>/<repo>/node_modules/aws-sdk-client-mock-jest/dist/es/jestMatchers.js" points to missing source files
Sourcemap for "/Users/<user>/<repo>/node_modules/aws-sdk-client-mock-jest/dist/es/vitest.js" points to missing source files

It looks like the sourcemaps are being shipped with the package but they are pointing to source TypeScript files that don't get shipped.

Reproduction

Run any tests that use this library with Vitest (might work with Jest too, but I'm not sure if it logs sourcemap warnings)
