Summary

Follow-up to #2427 (addresses #2426). FreshnessScorer now defaults current_year to the current year, but the LLM context docs still passed current_year=2024 in their examples. Readers who copy them get the old ranking: 2024 pages score highest, and newer pages score like undated ones.

This PR removes the hard-coded year from the examples, so they use the default. A short comment on the standalone example says that current_year defaults to this year and can be passed to score against another year.

Merge after #2427.

List of files changed and why

• docs/md_v2/assets/llm.txt/txt/deep_crawl_advanced_filters_scorers.txt - remove current_year=2024 from both FreshnessScorer examples and add a comment on the default.
• docs/md_v2/assets/llm.txt/txt/llms-full.txt - the same change in the same examples.

llms-full-v0.1.1.txt is the v0.1.1 snapshot, so it is not changed.

How Has This Been Tested?

Docs only. The examples use only weight, which is a valid argument before and after #2427. With #2427, FreshnessScorer(weight=...) scores against the current year (tested in that PR).
