patch 9.1.1522: tests: still some ANSI escape sequences in test output
Problem: tests: still some ANSI escape sequences in test messages output
Solution: update the cleanup regexp to also handle those ANSI escape
sequences: `<esc>|2h` and `<esc>|31H` like in this log output:
```
2025-07-05T20:02:47.6350409Z <esc>|2hExecuted 171 tests in 4.739708 seconds<esc>|31H
```
