ci: fix gemfury push for Node.js packages (#4097)

Fixed `ENEEDAUTH` when publishing npm packages to Gemfury.

The root cause is the script not accounting for NPM_REGISTRY URL having
a trailing slash, causing a double-slash in the generated `.npmrc` key
(`npm.fury.io/arrow-adbc-nightlies//:_authToken`)

**Test Plan**

Tested full gemfury package upload on my fork
- Pointed URL's to my own gemfury
-
https://github.com/kentkwu/arrow-adbc/actions/runs/23171042963/job/67325129419

Closes #4093.
