update npm packages

[nlsvgtr]

• update npm packages
• remove unused packages
• remove unused services

Critical issues have been solved. I propose to merge these fixes, and solve the rest later.

High risk issues remain in two packages:

• image-steam uses a vulnerable version of sharp; it can be easily updated. A PR is created; if the maintainer does not respond, we could fork the lib for now.
• mjml uses html-minifier which is no longer maintained. This will not be solved until the next major version of mjml, We may need to replace mjml. See High Severity Vulnerability in html-minifier mjmlio/mjml#2589

After that only three moderate warnings remain, due to a dependency in @kubernetes/client-node

The image-steam PR has been merged (though not published, so we're using a github link now).

All remaining high risk issues are due to MJML.
