P2 Badge Drop EOL 4.1 from backport targets

As of July 7, 2026, v4.1 is past its February 28, 2026 EOM and SECURITY.md marks 4.1 and earlier as EOL with no further fixes, but this updated contribution guidance still tells contributors to target v4.1. That sends fixes toward a branch the security policy says is closed; remove v4.1 from the maintained target list or explicitly mark it EOL in this section.

P2 Badge Keep stable BitBake recipe on the stable series

This recipe is the release recipe (it says it packages the latest stable release, while fluent-bit_git.bb covers active master builds), but this commit also documents v5.1 as the development line and v5.0 as the current stable series in MAINTENANCE.md. With PV set to 5.1.0, Yocto users consuming the stable recipe will fetch/build the development series, or fail before a v5.1.0 release tag exists; keep this recipe on the v5.0.x stable release until v5.1 becomes stable.
