Exclude look-alike characters from the generated API keys

Note that Nextcloud defines similar character set without ambiguous characters
as ISecureRandom::CHAR_HUMAN_READABLE. However, for some reason, that set
excludes also h, v, u, V, and U although those are not that ambiguous with any
other Latin letters or numbers.
