Update email address to community email address.

[DannyvdSluijs]

As it says on the tin. We should update the email address from jeroen’s work email to community@infi.nl. Same as we do on the Inficon website (https://con.Infi.nl)

When making changes be aware the email address is mentioned two times

• https://github.com/infi-nl/the-infi-way/blob/main/template.html#L382
• https://github.com/infi-nl/the-infi-way/blob/main/template.html#L400

Very fair! I'll kick off a quick out-of-GitHub discussion on this topic, and report back here with what we decided to do.
