Minecraft 26.3 support.

26.3 inserted three new packets, which shifted the team packet that glowing rides on from id 109 to 111. Every earlier build is refused by PacketEvents on 26.3 and disabled on startup.

Tested on a real Paper 26.3 server: the plugin enables cleanly, all glow teams are created and parsed correctly by the client, setting and clearing colours works, and the red/blue correction for clients on 26.1 and newer behaves as it should.

Why BETA: PacketEvents has the 26.3 support merged but has not released it yet, so this build bundles the official snapshot. Nothing in GlowAPI itself changed. The next version will be a normal release built against the PacketEvents release, with no further changes.

On 26.2 and older, 2.0.1 keeps working.
