feat: the update changelog covers every version you missed

Latest reads the last 10 releases in one request instead of only the
newest, so U and lazysecrets update --check show the changes of every
release since the running version, each under its version. Drafts and
pre-releases are skipped. A changelog taller than the screen is cut
with a pointer to the release pages.
