[BUG] Dataclass attributes specified with init=False cause error in pretty printing

[CollinHeist]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

Objects in pretty traceback printing which are dataclass objects with fields that are specified with init=False will cause an uncaught exception in the printing. See below.

from dataclasses import dataclass, field, fields

@dataclass(eq=False)
class BadDataclass:
    item: int = field(init=False)

# item is not provided
ob = BadDataclass()

# Displays all fields, including item
print([f for f in fields(ob) if f.repr])

# Raises an AttributeError since ob.item is not defined
print([getattr(ob, f.name) for f in fields(ob)])

This is specifically caused by this line of code.
