Archive old GHES feature matrix

[felickz]

The current view of a matrix for every version of GHES is too large.

1. Create an archive of the current matrix under /advanced-security/archive/GHAS-on-GHES-feature-matrix-2025.md
2. update the GHAS-on-GHES-feature-matrix.md to remove any release before 2024 (current year -1)

• Remove any columns for from the matrix for those releases
• Remove any rows from the matrix for those features which are fully released (every cell in that feature row has a ✅ )
