chore: fix the cspell ignore paths

The readmes/ directory went away with the docs rewrite in #1388, so
**/readmes/** no longer matches anything. Replaced it with
docs/versioned_docs/**, which holds frozen snapshots of the released
0.1-0.3 docs: they carry typos that cannot be corrected without
rewriting published pages.

Also added the domain terms that were left unlisted and switched two
British spellings to US so the dictionary can stay strict. cspell now
passes over all 1812 tracked md and css files.
