Description of the issue

In a Cypress config, setting "reporter": "junit" causes knip to incorrectly report junit as an unlisted dependency. Cypress bundles a junit reporter (see https://docs.cypress.io/guides/tooling/reporters) and does not depend on the junit package (I verified this by installing Cypress and then doing npm ls junit). The Junit functionality appears to be somewhere inside the Cypress package.

Here is the report knip produces:

Unlisted dependencies (1)
junit  cypress.config.ts

Looking at the plugin code for cypress, it appears to assume all listed reporters are package names, even though this isn't correct (not sure I've read this correctly!)

Workarounds

I can install the junit package but that seems wasteful. I could also switch to another Junit reporter (e.g. mocha-junit-reporter) but that also seems pointless.
