Update terminology: partial authentication → group-based access control

[mintlify]

Updated the CLI documentation to replace outdated "partial authentication" terminology with "group-based access control" to align with recent backend changes that removed the partial auth concept.

Files changed:

• installation.mdx: Updated two references to use "group-based access control" instead of "partial authentication" in the --groups flag documentation

Generated from leyland/remove partial auth from model @yangleyland

Note

Updates CLI docs to use current terminology for the --groups flag.

• Replaces "partial authentication" with "group-based access control" in installation.mdx for the preview (mint dev --groups) and validation (mint validate --groups) sections
