Bump sysroot to fix VCS ABI incompatibility

VCS shared libraries require glibc 2.33 symbols, but when using VCS within a conda environment, the conda-provided GCC attempts to link against conda sysroot that was previously too old to provide those symbols. We will need to bump this periodically in conjunction with OS updates if we were to keep using conda GCC for VCS.
