Add back diff from PR #3406 and bump toolkit docker default terraform version 1.5.2 -> 1.5.7

[mohitchaurasia91]

Adding back kubectl provider change from #3406 (incl in v1.45.0), reverted through #3573 (incl in hotfix v1.45.1)

Tested this change for toolkit docker default compatibility with #3406 kubectl provider change, work as expected for terraform version 1.5.7, so bumping default terraform version from 1.5.2 -> 1.5.7

This will sync the toolkit docker default setup with install dependencies doc

Used following command for local docker build for test purpose

docker build --build-arg CLUSTER_TOOLKIT_REF=v1.45.0 \
             --build-arg TERRAFORM_VERSION=1.5.7 \
             -t gcluster-terraform-1_5_7 .
