fae70ba00d ci: Better tidy errors (MarcoFalke)
Pull request description:
Currently tidy errors are not nice, because the user may have to scroll up to see them in a large block of text. See for example (before) https://github.com/bitcoin/bitcoin/runs/19670551485
Fix that by `tee`ing the output to a file and summarizing the errors in the end again. See for example (after): https://github.com/bitcoin/bitcoin/runs/22647850662
