docs: fix typo and update broken news/adoption links

[singhshresth26]

Summary

This PR fixes a spelling typo and updates two broken external links to their current live locations. Since these are trivial editorial corrections, they are submitted without a pre-existing issue.

Changes

1. Typo Fix: Corrected Uodates to Updates in content/en/resources/news.md.
2. Link Fix 1: Updated the Bottlerocket updater link in data/adoptions.yaml to point to the active main branch rather than develop, and removed its pattern from the ignore list in lychee.toml.
3. Link Fix 2: Updated the Linux Foundation announcement link in content/en/resources/news.md to point to its official URL on the CNCF website, and removed its pattern from the ignore list in lychee.toml.

Thanks @singhshresth26, this qualifies as a trivial editorial fix under our first-time contributor policy (#159), but the branch now conflicts with main. To get it ready for review:

• Rebase onto main (or merge main into your branch).
• Drop the Uodates typo fix; main already has it (Fix typo: Uodates -> Updates in news.md #167).
• Keep the two link fixes (the CNCF announcement URL and the Bottlerocket main-branch URL).
• In lychee.toml, keep the removal of the linuxfoundation.org exclude, but drop the Bottlerocket-exclude removal; that exclude is already gone from main.
• Run npm run check:links locally and commit the resulting .lycheecache changes; the required BUILD and CHECK LINKS check fails when new links lack cache entries.

Once that's pushed and CI is green, a maintainer will review.

Sorry for the delay, I have resolved the conflicts, updated the branch, and fixed the issues as requested.

Thanks for the clean PR. I adjusted the prose around the link so that it makes sense in the context of the new CNCF URL.
