chore: add script to update lts dependencies

[aaron-prindle]

Fixes #7922

Adds a script that automatically - fetches latest version of deps, uploads necessary files to GCS, and updates related Dockerfiles. Method used to get latest deps is flaky and should be double checked.

aprindle@aprindle-ssd ~/skaffold  [update-lts-dependencies-sh]hack/update-lts-dependencies.sh 
Updating kubectl to version: v1.27.1
Updating helm to version: v3.12.0
Updating kustomize to version: 5.0.3
Updating kpt to version: 1.0.0-beta.32
Updating gcloud to version: 430.0.0

WARNING: the method used to get deps comes from combination of Github latest release and latest git tag on a repo. These methods of getting the latest version of a binary are not error prone and should be manually checked.  For gcloud there is no api endpoint to check for the latest version so the output of 'gcloud version' is used asssuming the machine running this command has the latest gcloud version.  Manual modification of the script is required in cases where the version found by the script is incorrect.
