Chart request: validator activation queue length

[ryanberckmans]

Would it be possible to add a line chart for the validator activation queue length? The x-axis might be the date, and the y-axis might be the number of days in the future a validator will be activated if it was deposited on that date. Or the y-axis might be the number of validators that were waiting to activate on that date.

Validators deposited today will activate in nine days on Dec 12. It'd be interesting to see if this stat is trending upward or downward. https://eth2-validator-queue.web.app/index.html
