fix: pyfloat type error on none max value

[HugoJP1]

What does this change

Handle the combinations of specified digits and min and max values in a more advanced way for pyfloat.

What was wrong

There were a few issues that this PR aims to address:

• This line was throwing a TypeError if max_value or min_value was None

self.generator.random.uniform(0, max_value - min_value)

• This line would throw an error when needed_left_digits == sys.float_info.dig because the range was then invalid
• Giving in -(10**sys.float_info.dig + 1) as max value and 10**sys.float_info.dig as min_value can never succeed because of the following code at the end:

        if right_digits:
            result = min(result, 10**left_digits - float(f'0.{"0" * (right_digits - 1)}1'))
            result = max(result, -(10**left_digits + float(f'0.{"0" * (right_digits - 1)}1')))
        else:
            result = min(result, 10**left_digits - 1)
            result = max(result, -(10**left_digits + 1))

• The number of left and right digits were not always respected.

How this fixes it

• ValueError is raised if max_value or min_value is out of bounds
• right digits is set to 0 if the inferred left digits is already equals to sys.float_info.dig
• Rather than choosing only the left_number which then caused issues in trying to figure out a "right number" which could then end up being lower/higher than the configured max/min value, an int is chosen randomly between min and max values which are scaled up to have the length of left + right digits so that afterwards a . can be inserted in the right place.
• The previous adjustment code containing the TypeError is removed.

Fixes #1907

[HugoJP1]

This section aims to infer boundaries in the case where we don't have max_value or min_value.

[HugoJP1]

Renamed to temp rather than left because it is now doing both the right and left parts.

[HugoJP1]

This part is so that we can generate a number which respects these two constraints:

1. It must have a fixed amount of left digits
2. It can be either positive or negative.

In this case we need to choose two numbers, one in the negative side, and one in the positive. We then choose randomly between the two.
