.github: Synchronize release preparation steps

Two steps were unnecessary, remove them:
- GITHUB_TOKEN setup
- GOPATH setup

For the vast majority of releases, release managers do not need to
manually check the checkboxes of all of these steps, so convert them
into a list instead. Keep the checkbox for updating the release tool as
it is essential to keep this up to date.

Update this section for all issue templates to ensure consistency.
