Update for Nest 7

[michaelsogos]

Do you think is ok to update dependencies to nest 7.x ?

Hi @miaowing ,

Not a big issue, but each time i update a package with yarn it tell me:
nest-schedule@0.6.4" has incorrect peer dependency "@nestjs/common@^6.0.5".

It happens because i'm using NestJS 7.5.x 😄 .

Do you think is ok to update dependencies?

https://www.npmjs.com/package/@nestjs/schedule Why not try this.

I opened a PR to update it (#63) since we have the same issue

I found that nestjs 7 and 8 have its own scheduler that work pretty similar. I changed my code to use the integrated one.
