Pull request overview

Upgrades the bundled Microsoft ODBC Driver for SQL Server from 18.5.1.1 to 18.6.2.1 across all supported platforms (Windows x64/x86/arm64, macOS x86_64/arm64, Linux debian_ubuntu/rhel/alpine/suse for x86_64 and arm64). Updates the binary references, CI download URLs/verification commands, and license/release-notes files that ship with the wheel.

Changes:

• Update Linux .so filename from libmsodbcsql-18.5.so.1.1 to libmsodbcsql-18.6.so.2.1 in ddbc_bindings.cpp, test_000_dependencies.py, build.sh, and the pipeline ldd checks.
• Update PR validation pipeline to download the new MSI (linkid 2358430) and the new Alpine msodbcsql18_18.6.2.1-1 APKs/signatures (new download path 0b3d5518-...).
• Replace bundled Windows/macOS/Linux license files and macOS/Linux release-notes for the new driver version, and add a new license file for linux/suse/x86_64.

checked all 53 files. binary swaps look right across all 6 platform/arch combos, pipeline download URLs and ldd paths all point at 18.6.2.1, ddbc_bindings.cpp driver path on linux updated, tests match. one stale 18.5 reference in the pipeline but it's in a commented-out block (line 2311), not worth touching. encoding fix for the license files landed clean in the follow-up commits, french text and smart quotes render correctly in UTF-8. 100% diff coverage on the one code line. all 28 CI checks green. lgtm.
