docs: Disallow decimal literals with trailing dots

Browse Source 
Currently the documentation suggests that a decimal literal can omit the
fractional part [1]:

> Decimal fractional literals are formed by a `.` with at least one
> number on one side. Examples include `1.`, `.1` and `1.3`.

However, commit ac68710 (May 30, 2018) disallowed trailing dots that are
not followed by a number [2].

Using decimal literals of the form `1.` will actually result in a
`ParserError` and so the docs should no longer recommend this form.
