Redundant usage of %q RB-ST1123

The %q syntax is used to define a string literal with single quotes. It is unnecessary when the string does not contain any single quotes or when you want to use double quotes instead.

For example, %q{Hello world} is equivalent to 'Hello world', but %q{Hello's world} is necessary to avoid having to escape the single quote character: 'Hello's world'.

If you don't need to use single quotes or want to use double quotes, you can use other string literal syntaxes such as %{} or "".

For example, %"Hello world" is equivalent to "Hello world", and %{Hello world} is also equivalent to "Hello world".

Bad practice

%q("hi")

# Use `%q` only for strings that contain both single quotes and double quotes
%q(\\foo\\)

# Use `%Q` only for strings that contain both single quotes and double quotes, or for dynamic strings that contain double quotes.
%Q(hi#{4})

Recommended

'"hi"'

'\\foo\\'

"hi#{4}"
