build: update base image to Fedora 43

[piyush-jena]

Description of changes:

1. Update container image from Fedora - 43

Not contained in this update is an update to Go package. The update is necessary in aarch64 to fix an unit test. It will be part of a separate PR.

Testing done:
Container image update:

1. Compared the checksec result - it matched for all binaries
2. Compared the sizes - it matched for all binaries except mount and umount. This is okay because mount and umount retain the debug sections in their binaries post rpmbuild. As mentioned here: https://fedoraproject.org/wiki/Changes/StaticLibraryPreserveDebuginfo, Fedora 43 allows some additional sections of debug info compared to Fedora 41 which caused the 840 bytes size difference.
3. Built bottlerocket-core-kit (no changes), built bottlerocket-kernel-kit (requires update to package cert verification step for neuron package), built bottlerocket - instance boots, joins cluster, ran go-nodejs container in non-nvidia instance, ran nvidia-smoke-test on nvidia-instance (for both arches)
