Multiple Go-tests fail. E.g. RouterBGPVRF, RouterStaticVRFIPv4Unicast and RouterStaticIPv4Unicast

Cisco IOS XR Software, Version 7.9.2

> go version
go version go1.23.2 darwin/arm64

When testing #266 , the tests as described in #237 (comment) now fail. Even without these new commits.
Furthermore, the tests for RouterStaticIPv4Unicast (without the VRF) also fail. They all fail with element(s) not found: 'prefix'.

In the meantime, we have downgraded IOS-XR in our lab to 7.9.2, (possibly from 7.11.1) so it might be an incompatibility issue with this version. But my development laptop has changed as well.

I encounter the same error when testing on an old (v0.3.2 / Commit: 372a870) version:

Test RouterBGPVRF

Also the test from #246 (comment) fails on the current main branch.

Yes, we paused testing against 7.9.2 because there are some open issues wrt models and gNMI. All of the tests should work against 7.6 although this is pretty outdated by now.
