Better column_exists? docs

ghiculescu · web-flow · commit 14fde502dc1e · 2021-11-22T13:48:36.000-06:00
- Fixes a typo - rails#43687 (comment) - Gives another real life example (bigint) Still needs more work to try and make all this make sense (or to fix the root issue) but I wanted to put this up to get started.
