Regeneration II Beacons and new side effects for beacons

As of now, (at least on bedrock edition) you cannot add regeneration II to beacons.

You can only add regeneration I as a side effect.

I propose alongside strength, there should be regeneration I.

And, like other effects, it can be amplified by having a max level beacon.

Maybe, fire resistance or night vision could be added as new side effects as well, as they do not have a more powerful variant.
