bef110b92a changed the display for unexpected floats to always append a
".0" if there was no decimal point found in the formatting of the float.
However, this should only be relevant for finite (i.e., not NaN or inf)
values. The change introduced a test failure in the ordered-float
crate due to this:

The serialization implementation is heavily
inspired by the existing trait implentation for
`std::num::Wrapping<T>`.
The deserializing implementation maps input values
that lie outside of the numerical range of the
output type to the `MIN` or `MAX` value of the
output type, depending on the sign of the input
value. This behaviour follows to the `Saturating`
semantics of the output type.

Debugging a recent cargo-outdated bug, it would have been nice not to
wonder whether a rustc version change in GitHub's runner image was a
contributing factor.

Unit variant of externally tagged enum cannot be deserialized from the string
token by itself. It is ContentDeserializer + serde_test::Deserializer that makes
this possible, because serde_test::Deserializer produces Content::Str() from
Token::BorrowedStr() and ContentDeserializer produces unit variant from Content::Str().
The following tokens all produces Content::String(variant):
- Token::String(variant)
- Token::Str(variant)
- Token::UnitVariant { variant, .. }
Token::BorrowedStr(variant) produces Content::Str(variant) that was the real purpose to
use it in test in #933. This actually makes this test testing `Content` rather than type itself.
Correct way to represent enum one of:
- [xxxVariant { .. }]
- [Enum { .. }, xxxVariant { variant, .. }]
- [Enum { .. }, String(variant), <variant content>]
- [Enum { .. }, Str(variant), <variant content>]
- [Enum { .. }, BorrowedStr(variant), <variant content>]
