Missing Nodemailer option types

[gamedevsam]

Summary of proposed feature
When using typescript we cannot set all node mailer options without resorting to typecasting to any.

Purpose of proposed feature
Enable setting other node mailer options like secure, authMethod, tls options, etc.

Detail about proposed feature
Either add secure type, or better yet, extend the ProviderEmailServer type to extend SMTPConnection.Options type:

Potential problems
N/A

Describe any alternatives you've considered
I casted the server field to any. A suboptimal solution.

Additional context
Any other context, screenshots, etc.

Please indicate if you are willing and able to help implement the proposed feature.
Probably, if time allows.

This sounds like a good issue for the DefinitelyTyped repo, where TypeScript definitions for NextAuth.js currently live:
