improvement: Warn users not to use an example config without discussion

it's a good solution. however, do we really need to mention that someone uses a particular value? just below, in the section about maxColumn, we explicitly caution against values above 100...

intellij applies 120 as a "hard right margin" (i e., maximum), regardless of language, with the option of adding the so-called "visual guides" at additional stops.

and its original -- and, presumably, primary -- language is java, which has only one formatter (Google Java format) that uses the value of 100 and allows no customization.

not a single formal language style, for scala or Java, which can be found online uses the value of 120 (scala-lang sort of mentions 80, while several others set it to 100).

and, as I mentioned, intellij's global value is really a "nobody should go beyond that since it doesn't fit the screen anymore" rather than "let's pack as many characters as possible before this marker".

in addition to "you should discuss internally" comment, but without a specific value suggested, we can change the example to something ridiculous, like 1234, so that no sane person uses it.

as i mentioned above, published standards, specifically for scala, actually use 100, and intellij's 120 is not specific to scala, not published and not even used for java.

@kitbellew 💯 🙏 yes please!

I changed the example and made the additional comment about the specific problem users might encounter.
