build: update NPM lockfile to v3

[dennisameling]

While working on #108, I noticed some warnings in the npm install command:

npm warn ERESOLVE overriding peer dependency
npm warn While resolving: @typescript-eslint/[email protected]
npm warn Found: [email protected]
npm warn node_modules/eslint
npm warn   dev eslint@"^9.15.0" from the root project
npm warn   2 more (@eslint-community/eslint-utils, eslint-plugin-jest)
npm warn
npm warn Could not resolve dependency:
npm warn peer eslint@"^7.0.0 || ^8.0.0" from @typescript-eslint/[email protected]
npm warn node_modules/eslint-plugin-jest/node_modules/@typescript-eslint/utils
npm warn   @typescript-eslint/utils@"^6.0.0 || ^7.0.0 || ^8.0.0" from [email protected]
npm warn   node_modules/eslint-plugin-jest
npm warn
npm warn Conflicting peer dependency: [email protected]
npm warn node_modules/eslint
npm warn   peer eslint@"^7.0.0 || ^8.0.0" from @typescript-eslint/[email protected]
npm warn   node_modules/eslint-plugin-jest/node_modules/@typescript-eslint/utils
npm warn     @typescript-eslint/utils@"^6.0.0 || ^7.0.0 || ^8.0.0" from [email protected]
npm warn     node_modules/eslint-plugin-jest

By doing a simple npm update locally, the issue has disappeared. The update to lockfile v3 also greatly reduces the size of the lockfile.

I just had a look at the documentation and it seems that v3 was introduced with npm v7 (with v2 being a more bloated variant, but backwars-compatible with npm <v7). This corresponds to node.js v15, so I think we're good ;-)
