A0-2967: Update kustomize to 4.4.1 (#1331)

# Description

Bumps kustomize version from `3.8.6` to `4.4.1` to match the version
used in ArgoCD.
Bumps `setup-kustomize` action version from `v1` to `v2` (that one comes
from Dependabot PR). According to the v2 release notes, there are no
breaking changes.

## Type of change

Action `setup-kustomize` is used in deployment workflows for devnet,
testnet and mainnet.

## Tested

A temporary workflow has been created where apps repository was checked
out and `kustomize build .` was executed in one of the app's overlay to
check if YAML, with kubernetes resources, gets properly generated.
