Enhance logic of LowCacheTime to minimize noise.

`❗️ Warning: Low cache expiry time of "wp_rand( 5 * MINUTE_IN_SECONDS, 10 * MINUTE_IN_SECONDS )", it is recommended to have 300 seconds or more (WordPressVIPMinimum.Cache.LowExpiryCacheTime.LowCacheTime).`

`wp_cache_set( $latest_blocks_cache_key, $latest_blocks, null, wp_rand( 5 * MINUTE_IN_SECONDS, 10 * MINUTE_IN_SECONDS ) );`

## What problem would the enhancement address for VIP?
It is very common for clients to use constants HOUR_IN_SECONDS, DAY_IN_SECONDS, MINUTE_IN_SECONDS and to also vary the duration to not have cache stampedes.

## Describe the solution you'd like
Can we enhance the logic of the ruleset to not flag for common usages?
