[instrumentation-nestjs-core] potential future build failure, Node.js <20 is not supported

[pichlermarc]

Description

Builds on main receive warnings due to @nestjs/core@11 being not supported on Node.js < 20. If Nest.js updates are published that actually break, this will lead to a release-blocking issue.

Introduced in #2685
