chore: update labels (#47904)
### What?
Syncing https://github.com/vercel/next.js/labels with the bug report template.
### Why?
We've got some OS-related reports so it would be nice to be able to filter on that.
### How?
The label description is added as a select option to the template, which then matches one of the labels https://github.com/vercel/next.js/labels
