Add grow and shrink aliases (tailwindlabs#5733)

This adds `grow-*` and `shrink-*` utilities as aliases for `flex-grow-*` and `flex-shrink-*` since those names are unnecessarily verbose. We will stop documenting the long form ones and consider them deprecated.

```diff
- <div class="flex-grow-0 flex-shrink">
+ <div class="grow-0 shrink">
```
