DO NOT MERGE - [workers] support for modern crypto algorithms

[thibmeu]

Summary

This updates the documentation to integrate support for modern cryptographic algorithms. Waiting on cloudflare/workerd#6872 to be merged and deployed.

Documentation checklist

• Is there a changelog entry (guidelines)? If you don't add one for something awesome and new (however small) — how will our customers find out? Changelogs are automatically posted to RSS feeds, the Discord, and X.
• The change adheres to the documentation style guide.

👉 Fix in your agent 👈

Fix the following review findings in PR #32272 (https://github.com/cloudflare/cloudflare-docs/pull/32272).

Before making changes, review each finding and present a brief summary table:
- For each finding, state whether you agree, disagree, or need clarification
- If you disagree (e.g. the fix requires disproportionate effort for minimal benefit,
  or the finding is factually incorrect), explain why
- If you need clarification before deciding, ask those questions
- Then share your plan for which issues to tackle and in what order

After triaging, follow this order:
1. Post a comment on this PR for any findings you are skipping, with the finding ID and your reasoning.
2. Then commit the fixes for the legitimate findings.

The comment must come before the commit — the bot reads PR comments when a new
push triggers a review, so skip comments posted after the push will be missed.
