Chore/revert to old typedoc version

[saltcod]

What kind of change does this PR introduce?

Rolls back the version of typedoc. Details: https://supabase.slack.com/archives/C023E4L60R3/p1667872282490169?thread_ts=1667813641.749009&cid=C023E4L60R3

tl;dr — the newer version stores comments as comment.summary instead of comment.shortText which breaks the docs generation for this spec.
