Conflicting peer dependency: vue@2.6.14

[MartinX3]

Using vue 2.7 I can't install pinia, because of this issue.
Probably because of

vue-demi/package.json

Line 40 in dbe21e4

"vue": "^3.0.0-0 || ^2.6.0"

Also if I force install pinia it tells me at buildtime that the dep vue-demi is missing which I also need to force install.

I am not sure what we can do about it. If you do, PR welcome.
