feat(check-tag-names): allow rejecting normally valid tag names and/or providing custom error messages when suggesting tags to reject or replace (fixes #108)

Reporting normally valid tags may be of interest for tags like `@todo`. This is implemented by allowing the user to set targeted `tagNamePreference` tags to `false` or to an object with only a `message` and no `replacement`

Custom messages for `check-tag-names` are implemented by allowing the user to set targeted `tagNamePreference` tags to an object with `message` and `replacement` (mirroring `preferredTypes` behavior). Note that for other rules leveraging `tagNamePreference` (via `utils.getPreferredTagName`) to find the user's preferred tag name, the `replacement` will be used in the likes of error messages but not the `message`.

Also, for various (param, return, and description-related) rules which have used `tagNamePreference` (via the `utils.getPreferredTagName` utility), report to user if they have blocked (probably inadvertently) and not indicated a replacement for the relevant tag needed by the rule in the `tagNamePreference` setting.

Also, ensure `require-param-name` and `check-examples` report preferred tag name (not necessarily `param` or `example`, respectively) and err if `example` is a rejected tag
