test: update vitest version & fix typo in url

[jumpy-cat]

Description

Was debugging a cryptic test failure higher up the stack when I noticed the vitest version being used is 3 years old. Bumped that to the most recent stable version, which resulted in an better msg and allowed me to find the root cause: a typo in a url. The test passed historically because parseInt would take only the prefix and ignore the rest but the process of migrating to documented resulted in something more strict.
