Slow lint warnings: disable by default, allow enabling by config

[AriPerkkio]

Currently when a file takes more than 5 seconds to lint, a warning is logged. This is considered as "slow lint". While this may be useful for rule development, it is causing false positives and verbose logging when testing rule configurations. Rule configurations typically have multiple rules enabled.

• Disable slow lint warnings by default.
• Allow users to enable slow lint warnings throught eslint-remote-tester.config.ts.
• The default value should be null. Allowed values are numbers.
• The current log level "warning" is preserved. No changes here.
