Autodelete wp-rocket-debug.log.html if it grows bigger than a specifc size

Is your feature request related to a problem? Please describe.
When we enable WP_ROCKET_DEBUG, the wp-rocket-debug.log.html file can grow quickly, specially if preload is enabled and there are multiple optimizations running.

If for any reason the WP_ROCKET_DEBUG constant is not removed, it could grow without a limit causing multiple issues.

• Causes CPU issues, WPR Settings page fatal error when debug file is so large even though debug mode is disabled #6581
• could grow over the GB, using too much server disk space
• random errors https://wp-media.slack.com/archives/C056ZJMHG0P/p1712955511311249

Describe the solution you'd like
We could delete the file if it grows over a reasonable size, I think 20 or 30 MB should be more than enough to troubleshoot any kind of case.

Describe alternatives you've considered

• autodisable WP_ROCKET_DEBUG if the file size is too big.
• autodisable WP_ROCKET_DEBUG after some time (1 or 2 hours)

Additional context
