git show-ref in check_remote_branch is not working at all, because the GitHub Actions checkout fetches a git repo with only depth 1 by default. That means only main branch is available, not any other remote branches. As a result, git show-ref always fails. Fix that by checking for remote branches by git ls-remote.

# Generates a changelog entry. Usually the changelog entry is in a

# following form:

# - <name> ([<version>](<url>))

# Thus first three parameters of this function should be the name,

# generate_update_changelog Go 1.19.4 'https://go.dev/doc/devel/release#go1.19.4' go \
