🐛 Bug in `activateLevel.js` middleware

[GianfrancoBazzani]

Seems that url analysis to support level addresses and level number in the /level subpaths is not parsed correctly and results in unexpected behavior on many situations.

You can reproduce the bug on prod by accessing an nonexistent page in the /level subpath (e.g., https://ethernaut.openzeppelin.com/level/sadfasdf). The browser shows a 404 URL, but the error message is not being shown properly.

Correct 404 page:
