tools: fix release URL computation in update-root-certs.mjs

Previously this would compute the release tag to be something
like FIREFOX_134_0.2_RELEASE which would not lead to a valid
URL, failing to pull the latest NSS updates from the Firefox
release. It should replace all the dots with underscores to
compute something like FIREFOX_134_0_2_RELEASE instead.
