fix cypress 10 change - do not exit without cypress.json

[plaschczek]

With cypress 10 all config json files are js files, so no cypress.json exists.

As quick fix do not exit if no cypress.json found.

Hello @ma-jahn @jkvim , will this be approved and merged? or maybe there will be another decision provided?

Because with cypress v10 and higher there are no more cypress.json file in the project, they now use cypress.config.js instead.
But even if I will add the cypress.json with only reporter config there - Cypress shows me an error Cypress no longer supports cypress.json, please remove it from your project.
So we definitely need a new version or at least a workaround.

Great job, but I don't have write access to this repo.
