Bump dependencies to fix CVEs

[RinZ27]

Hey maintainers,

I noticed pygments and tensorflow-io-gcs-filesystem in requirements.txt are lagging behind a few versions. The current versions have some known vulnerabilities (related to AST parsing and file handling) that could be risky if left unchecked.

I've bumped them to the latest patched releases (3.2.5 and 0.38.1). Did a quick local check and everything seems to load fine, but let me know if you hit any weirdness with the new versions.

Cheers.

Gonna close this one. Realized I jumped the gun on these version numbers—they aren't actually live on PyPI yet. Must have misread the changelogs.

My bad, sorry for the ping!
