Better Brightness Slider Respawn

Modify the player’s gamma brightness to make the world brighter

# The feature is ported from [Better Brightness Slider](https://modrinth.com/mod/better-brightness-slider)

## Ported the mod from the lower version 1.20.x to the NeoForge version 1.21

Better Brightness Slider expands the default brightness slider, making it range from -100% to 1200% (fullbright) instead of 0% to 100%. It’s a clientside mod, so it isn’t required on servers.

Upgrade version to 1.21 NeoForge.

The mod should be compatible with Optifine and Embeddium.
