ci: drop misspellings from the CSpell project dictionary

Remove the 126 misspelled words from cspell-project-words.txt: the 112
words already listed in flagWords, plus 14 more found while reviewing the
dictionary (addresseses, Changs, certains, condeintel, ERRROS, gorelaser,
lobal, Redict, settingscasacde, sguqery, Sourcegraphs, Stablechore,
theyre, Wofli). The words that still appear in non-generated docs are
fixed in #1855 and #1873; the rest only occur in generated files that
cspell.json already ignores.

Keep eror, functio, and stabili in the dictionary and stop flagging them:
eror is Sourcegraph's log level token (lvl=eror), and functio and stabili
are truncation artifacts in verbatim command output, not misspellings.
