feat(LAB-496): lower required Node version to 18

Require Node v18+

Description:

As @ysellami pointed out, some of our modules are using version 18 of Node so the JsonWebSignature2020 library’s Node version can be downgraded to version 18 as a minimal requirement. The build and tests run fine with Node 18.

Please note that Semantic Release is raising some warnings which we will have to keep an eye on in the case of an issue 👀
