data URI is reported as a missing dependency

[ljharb]

Describe the bug
See https://bundlephobia.com/package/has-dynamic-import@2.1.0. See Ignoring the size of missing dependency data:text.

To Reproduce
Publish any package with dynamic import of a data URI.

Expected behavior
The size of a data: URI is already counted as part of the code, and there's nothing to add to package.json, so this message need not appear.
