fix(revealjs): normalize EOL in vendored-asset drift test

The test byte-compared the include_str!-embedded reveal assets against
the npm dist copy. On a Windows checkout, core.autocrlf rewrites the
committed-LF vendored files to CRLF on disk, so the embedded bytes gain
CRLF while the npm copy stays LF -- a false mismatch on line endings
alone. These assets are served verbatim and CRLF vs LF is irrelevant to
browsers; the test's job is to catch content drift when reveal.js is
bumped, not line endings. Normalize both sides before comparing so only
real drift fails.
