ci: tolerate hyperlink false positives in MyST /development/ site

netlify-plugin-checklinks (hyperlink) now traverses the full cookie
site and flags two non-issues: its parser fails on MyST's bundled
mermaid chunk, and it reports valid in-page fragments as broken when
the target goes through MyST pretty-URL normalization. Mark both as
todoPatterns so real broken links still fail the build.
