fix(docs): use a plain year range in NOTICE copyright (#6983)

### What changes were proposed in this PR?

Per ASF policy [1], the NOTICE copyright line should use a plain year
range, not "and onwards". Changed `Copyright 2025 and onwards The Apache
Software Foundation` to `Copyright 2025-2026 The Apache Software
Foundation`
in the root `NOTICE` and all `*/NOTICE-binary` files.

Closes #6981. To be backported to `release/v1.2` for RC4.

### How was this PR tested?

Text-only change; CI license/NOTICE checks pass with no generator drift.

### Was this PR authored or co-authored using generative AI tooling?
