Suppress Fetch API Experimental warning

[epaminond]

On project start I'm getting a warning:

(node:398315) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time

It's node 18.0.0 and I assume this warning is coming from mailgun.js bug fixed in version 3.5.7.

nodemailer-mailgun-transport depends on mailgun.js 3.3.0 - so possibly this could be the source. Would it be possible to upgrade dependency to at least 3.5.7 or newer?

Maybe this can be closed since Mailgun.js was upgraded to > 7 in September 2022:
