Bump docker api version

[devanshuVmware]

1. Bump golang to 1.25.7

2. Bump carvel imgpkg to v0.47.2 and vendir to v0.45.2

3. The default docker engine version has been bumped to 28.0.4 which supports min docker version as 1.44.0
   Some of the kbld tests wrt buildx, ko and pack cli wer using old cli versions.
   This has been fixed by specifying a min docker api versin for client and server (in minikube)

4. Also it necessitates the bump for bazel and its associated rules binary version in WORKSPACE
