📜 Background

Previously the release workflow was failing for every release created here: https://github.com/secretkeylabs/xverse-web-extension/actions/workflows/release.yml?page=2

This PR fixes that workflow and the idea is so upload built release artifact to the releases page like here: https://github.com/secretkeylabs/xverse-web-extension/releases/tag/v0.13.0 (needs testing on next release)

This PR also saves the built output of each build workflow run, so that any tester can download the build directly from either the workflow run here: https://github.com/secretkeylabs/xverse-web-extension/actions/runs/5460899929
or as a comment on the PR (needs testing after merge)
