New documentation website: go-mail.dev

[wneessen]

While the GoDocs documenation is great, it can sometimes lack a bit detail. Especially when you are new to Go and/or the library it might feel a bit overwhelming to get started. Therefore I thought it might be a good idea to introduce a documentation website, that provides more in-depth knowledge and provides easy to use examples.

Therefore, yesterday I've created a new documentation website project for the go-mail library: go-mail-website. The website is built with Hugo and the GeekDocs theme and looks great (IMHO). It is automatically published via GH actions to go-mail.dev.

For now there is only a landing page and a getting started page, but hopefully we can add much more documenation there soonish. I hope you like the page and also looking forward to contributions.
