Allow latest version of New Relic to be used

**Is your feature request related to a problem? Please describe.**
The current version of New Relic used in `@envelop/newrelic` is very badly out of date. We've been experiencing issues with the instrumentation and missing spans and other anomalies that New Relic support claims may be related to the outdated agent version.

Unfortunately we aren't able to upgrade the version of New Relic in our installation to test because [`peerDependencies` tops out at major version 8](https://github.com/n1ru4l/envelop/blob/9a62a42498d818388cc33784523c50497a4853e9/packages/plugins/newrelic/package.json#L52).

Oddly enough, the [`devDependencies` is already using New Relic version 9.x](https://github.com/n1ru4l/envelop/blob/9a62a42498d818388cc33784523c50497a4853e9/packages/plugins/newrelic/package.json#L64) -- but meanwhile New Relic [is on version 10.5.0](https://www.npmjs.com/package/newrelic?activeTab=versions)

**Describe the solution you'd like**

Expand the peer dependencies up to the latest major semver.

**Additional context**

Our team uses New Relic for our production apps, though we are still very early in our GraphQL adoption. More than happy to help out if there's need for testing or dev assistance to more closely follow New Relic's releases.

Start in packages/plugins/newrelic/package.json and compare the peerDependencies range with the New Relic version already listed in devDependencies. Update the peer dependency range to allow the requested newer major version, then verify that the package installs and its existing checks pass with that version.
