Kubectl bash Autocomplete is broken with latest bash-completion version

[abhijit-dev82]

What happened:
kubectl autocomplete is broken with the below error
"bash: _get_comp_words_by_ref: command not found"
with 2.14 Bash-completion version. From the bash-completion docs "_get_comp_words_by_ref" seems to be a deprecated API.

What you expected to happen:
Bash Autocomplete to work as for older versions.

How to reproduce it (as minimally and precisely as possible):
Install latest "bash-completion" package and try out "kubectl" autocomplete.

Anything else we need to know?:

Environment:

• Kubernetes client and server versions (use kubectl version):
  Client Version: v1.30.5+vmware.3-fips
  Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
  Server Version: v1.30.5+vmware.3-fips
• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release): Photon 5

kubectl relies on spf13/cobra with regards to bash completion and as far as I can see, this function is only being used in here https://github.com/spf13/cobra/blob/main/bash_completionsV2.go#L51
I'd recommend opening an issue in https://github.com/spf13/cobra to be triaged.
