♻️(helm) extract make command in a script

Existing make command wasn't working on Mac. Fixed it, plus
refactored it in a proper script, so we can share it among
projects, as for the build kind cluster one.

External secrets are created in a dedicated namespace, to avoid
duplicating them if we spawn several LaSuite applications on the
same local stack.
