Change `*ReplacesDocs` setting defaults to `true`

[brettz9]

I think we should change the defaults of allowOverrideWithoutParam, allowImplementsWithoutParam, and allowAugmentsExtendsWithoutParam overrideReplacesDocs, implementsReplacesDocs, augmentsExtendsReplacesDocs (their non-deprecated replacements) to true, as this is I think a pretty rational loosening.

Actually, on further thought, I'm not sure augmentsExtendsReplacesDocs should always be true, and the others are already true by default.
