Refine: What is "The Triple Halvening"?

**PRECIEVED ISSUE**
The answer to **What is "The Triple Halvening"?** Has outdated "current projections" link and lacks explanation as to why issuance will drop (and what is the mechanism). Additionally, it suggests BASEFEE burn may turn issuance negative; however, it leaves the reader without any data.

**SOLUTION**
- Describe the relationship between the number of ETH staking and the rewards. i.e. How the number of stakers affects the rewards.
- Describe the current number of stakers (and date) and speculate the projected number of stakers at the merge.
- Build upon the first two points to enlighten the reader why a "triple halving" is anticipated. (similar to current wording)
- Reference a link to view/monitor ETH burn.
