DEPR: Clean up list of deprecations from prior versions
Log for previous deprecations, once they are actually removed, move the issue to #13777 

We try to keep these for *three* major versions as actual deprecations. e.g. deprecate in 0.17, 0.18 & 0.19 get the warning, removed in 0.20.

## 0.24.0
- [x] #24596 `__array__` for tzaware Series/Index (0.24.0)
