Andrey Avtomonov 35e8331a22 ci: normalize star-history.svg trailing newline
The star-history refresh workflow committed the API's SVG verbatim, but the
response has no trailing newline. Because the refresh commit uses [skip ci],
the file never ran end-of-file-fixer at commit time, so pre-commit's
`--all-files` run failed end-of-file-fixer on every open PR (e.g. #240), even
PRs that never touched the file.

Normalize the downloaded SVG to exactly one trailing newline in the workflow
(idempotent, so the "unchanged" guard still works), and fix the currently
committed file so open PRs go green now.
