Document the process and migration helpers for converting int columns to bigint
With #292841 (closed) and #292874 (closed), we are adding new migration helpers for converting int columns to bigint and a new background migration that could be helpful for other use cases as well.
We should add documentation for them and the conversion process once we have fully tested them and successfully used them in the migrations for addressing the PK overflow risk for the events
table (#288004 (closed), #288005 (closed)).
The documentation should include
- What to expect
- Troubleshooting (e.g. retry, pause, etc)
