build: add missing dependencies to deploy-projectsveltos target

[emilkje]

The deploy-projectsveltos make target was missing required dependencies
(ENVSUBST and KUBECTL) which could cause the target to fail when run
independently. This fix ensures all necessary tools are available before
executing the target.

Fixes: #1401

LGTM

Thank you

@emilkje would you please mind changing base to main? We dont use dev anymore. Instead main is used as the development branch and when ready to release we create a new branch (like release-1.1) and then from there we create the release.

Sorry for not noticing it before (and if there is any part of documentation that still refers to dev, please let me know so I can fix it)

Thanks

The base branch was changed.

I've rebased the PR branch to main and changes the base as requested. I read the CONTRIBUTING.md guidelines and was tripped up by Contributing point 5 and the branch descriptions. I've highlighted the text below indicating the use of dev branch.

5. Create a pull request to the dev repository.

Projectsveltos repos have three types of branches: the main branch, the dev branch and release-X branches.

The dev branch is where development happens. All the latest and greatest code, including breaking changes, happens on dev.

Thank you @emilkje

Thanks for sharing that. We forgot to change it (we used to develop in dev). So that is also something to update. Will fix it.

Thank you!
