Remove unused dependencies

[javierjulio]

As promised from #49 this is a follow up to remove unused dependencies as I noticed some while working on that PR.

I tried addressing some security updates but any seem to break CI, although running tests locally is successful. Addressing the many outdated dependencies should be done individually. I won't be able to contribute there as I'm not familiar with Typescript and Jest which have the most.

@cakeinpanic as mentioned in #49 this is a follow up to help reduce the number of dependencies and those reduce the lock file size. CI is green with this change and tests pass locally as well.

Hi, I don't see the reason to remove engines-ok dependency since on my laptop which has node18 installed globally it actually did prevent the build. Please bring it back or provide another solution which would do the same job

@cakeinpanic no worries, I dropped that commit so it remains in place. This is now ready.
