feat(crawler): add separate timeout for wait_for condition

Adds a new wait_for_timeout parameter to CrawlerRunConfig that allows specifying
a separate timeout for the wait_for condition, independent of the page_timeout.
This provides more granular control over waiting behaviors in the crawler.

Also removes unused colorama dependency and updates LinkedIn crawler example.

BREAKING CHANGE: LinkedIn crawler example now uses different wait_for_images timing
