chore: remove all Gemfury references from CI and build scripts

Packages are now published to GitHub Pages via the
update-package-repo workflow, making the Gemfury publisher
completely redundant.

- Remove GoReleaser fury.io publisher block
- Remove FURY_TOKEN export from build.sh
- Remove GEMFURY_PUBLISH_TOKEN from publish workflow
- Remove gemfury-publisher context from CircleCI
- Update CircleCI + GitHub Actions apt sources to new URL
- Remove "like Gemfury" comment from update-package-repo workflow

The GEMFURY_PUBLISH_TOKEN secret can now be removed from GitHub.
