fix(e2e): 查最新 release 时 gh 出错让步骤失败，只有 release not found 才跳过发布版任务

# find_release: `gh release view` with no tag answers with the newest release that is not a

# prerelease, the one the installer's release channel resolves.

#

# An empty tag skips the readme and upgrade jobs, green. Only gh's own `release not found`

# means there is no release; any other failure (a token it refused, a rate limit, a network

# error) fails the step, or every release's upgrade would go untested without a word.
