Set min supported node at 16

nextcloud/standards#1

Node 16 ships npm 8 since 16.11.0.
I suggest we just leave npm to 7.0.0 as this is the minimum supported. Devs can still use npm 8 if they want :)

Everyone on board?

Default is the wrong word. Min-supported is more fitting.

Sorry, this is not up to debate here ^^"
This issue is about raising from 14 to 16 prematurely

Nonetheless we can also discuss about raising min-NPM to 8 as well, removing support for 7. But I don't see the reasoning behind this as node16 ships both npm 7 and 8

Please read nextcloud/standards#5

Ok, so talking only about the node version, i'm fine with this. 😉

I am fine with raising the node version to 16.

On a side note, i would also prefer no warnings when using a supported npm version 😉

Devs can still use npm 8 if they want :)

But this will give warnings, since npm 8 is not compatible to ^7.0.0. What about setting NPM_VERSION: "^7.0.0 || ^8.0.0", then all node@16 installations (e.g. official docker container) will work just out of the box?
