Enable forbidigo linter (#24278) 
Enable [forbidigo](https://github.com/ashanbrown/forbidigo) linter which
forbids print statements. Will check how to integrate this with the
smallest impact possible, so a few `nolint` comments will likely be
required. Plan is to just go through the issues and either:

- Remove the print if it is nonsensical
- Add a `//nolint` directive if it makes sense

I don't plan on investigating the individual issues any further.
