Incorrect literals in FormattedValue

[JoshuaGlaZ]

FormattedValue (fstring) in noworkflow are incorrectly capturing entire string literals instead of parsing and capturing only the literal parts

f"Hello, my name is {name} and I am {age} years old."

will give values

name	type
f"Hello, my name is {name} and I am {age} years old."	fstring
f"Hello, my name is {name} and I am {age} years old."	literal
{name}	fvalue
f"Hello, my name is {name} and I am {age} years old."	literal
{age}	fvalue
f"Hello, my name is {name} and I am {age} years old."	literal

but the correct literal should captured separately the formatted value (fvalues), as demonstrated in the example below using ast.dump:

Module(
  body=[
    Expr(
      value=JoinedStr(
        values=[      
          Constant(value='Hello, my name is '),
          FormattedValue(
            value=Name(id='name', ctx=Load()),
            conversion=-1),
          Constant(value=' and I am '),
          FormattedValue(
            value=Name(id='age', ctx=Load()),
            conversion=-1),
          Constant(value=' years old.')]))],
  type_ignores=[])

In noworkflow, the equivalent representation should be

name	type
f"Hello, my name is {name} and I am {age} years old."	fstring
"Hello, my name is "	literal
{name}	fvalue
" and I am "	literal
{age}	fvalue
" years old."	literal
