Update minimist version to fix security issues

[Twinbird24]

One of the dependencies used in this project, minimist, should be updated from 1.2.5 to 1.2.6 to include this security fix.

I get a dependabot warning that this is a critical security vulnerability, but now can't update due to this package hard-locking minimist's version. There also already is a PR to update this dependency: #710. Maybe somebody can have a look at this with some priority?

Also it might be worth considering to use a progressive lock (e.g. ^1.2.6) instead of a hard lock for minimist (and other dependencies) instead.
