chore: update dependencies, remove gitorious support, drop Node.js <= 17

* Fix #57: Bump supported Node.js engine from 4.0.0 to 18.0.0

* Test & update some devDependencies

* Fix #58: Remove Gitorious features

* Restore missing close parens

* Fix #56: Deprecated package warnings

Note: some outstanding warnings due to cliffano/bagofrequest#6

* Update Node.js versions to test against

* Use 20.4 as the max test version since mock-fs currently fails on higher versions
(possible related to tschaub/mock-fs#377)

* Remove unused file with output of `npm ls --all`

* Update sinon & mock-fs versions
