Use NodeJS v20 (LTS) (#249)

* Removed Mocha and nyc dependencies alongside with related config files. Introduced jest and adapted tests. Updated typescript to latest (with some other development dependencies).

* Reduce line coverage threshold by 1% due to coverage tool differences

* Add "text" coverage reporter

* Use NodeJS v20 (LTS)

* Update checkout and setup-node GitHub actions versions to newer
