[R] SystemRequirements documentation incorrect for cmake version

[eeeggg]

Describe the bug, including details regarding any error messages, version, and platform.

The DESCRIPTION file states:
SystemRequirements: C++17; for AWS S3 support on Linux, libcurl and openssl (optional); cmake >= 3.16

But the actual build requirement is cmake >= 3.25.

This causes build failures when users rely on the documented requirements.

Environment:

• R version: 4.5.0
• arrow version: 20.0.0.2
• Platform: al2023 (Amazon Linux 2023)

Component(s)

Documentation, R

Thanks for raising this, it seems we forgot to update when we merged:

• GH-44950: [C++] Bump minimum CMake version to 3.25 #44989

I've created a PR to update the SystemRequirements.
