Correct spelling of sub-class > subclass and over-ride/over-ridden > override/overridden

[garrett-eclipse]

Hello,

While updating #46418 I noticed the use of over-ridden and sub-class which are more appropriate as overridden and subclass.

For subclass if you look up OOP languages (PHP/Java/etc) all official documentation uses subclass without a hyphen;
​https://www.php.net/manual/en/language.oop5.inheritance.php

For override;

In general, use a hyphen to separate repeated letters in a compound word - re-emergence, co-operative, film-maker, night-time - but there are some exceptions, including overrun, override, overrule, underrate, withhold. As usual, consult the Oxford English Dictionary if in doubt.
