Issue:
Fix failing plugin tests - `ts-mocha` compatibility issue
These three tests from `test/plugin/plugin.test.js` started failing since we upgraded all our files from CommonJS + JS to ESM + TS. This is due to `ts-mocha` tripping up with the way our `PluginLoader` works. Note that **this issue is only reproducible in Node 18 to 21**, the problem is gone in Node 22 due to interoperability improvements.

### Possible solutions:
- Run the CI in Node 22, and enforce Node 22 usage
  - May cause problems with users that cannot upgrade Node for certain reasons
  - By far the easiest fix

### Things I've tried: 
- Fixing the plugin implementation so that the `require` in the culprit code is avoided 
  - Spent a few hours trying to refactor the import (by delaying imports, etc.) without luck
- Fixing the `ts-mocha` execution so that it uses `tsx` loader under the hood
  - Also didn't work for me, however, I can't remember why

### Current solution:
Right now, we're simply skipping the three tests, since they do pass when executed in Node 22 (and they don't throw the `ERR_REQUIRE_ESM` error when executed via `tsx`).

Hints from issue comments:
@kriswest: Node 18 is EOL (last month?), however 20 has a year to go in maintenance unfortunately...
