In @.changeset/olive-wolves-love.md at line 5, Update the changeset copy that
currently reads "allows additional configuration options when creating an openAI
client" to use the correct brand casing "OpenAI" (i.e., change "openAI" →
"OpenAI"), and scan the same .changeset entry for any other occurrences of
"openAI" to correct them for consistency.
