Fix for the npm error @ step 4 & 5

[vaibhavppandey]

issue

So I was on this course and the jobs failed where it had to install the npm packages.

why (what I came up with atm)

the versions specified for the packages in package-lock.json & package.json were old and deprecated.

my solution (being a newb)

remove the package-lock.json & specify the versions from for e.g. '^7.3.1' to '*' for all the packages in package.json
and above the npm install, add npm update --save in files deploy-prod.yml & deploy-staging.yml. This would put right version and fix the issue

final thoughts

kindly fix the issue, @heiskr or the other active maintainers for this course. Also, thanks for this amazing course. Got to learn a lot ❤️
