Converting an infinity float/double literal to Decimal raises a bare decimal.InvalidOperation #4286

Apache Iceberg version

main (0.12.0)

Please describe the bug this is related to

float('inf') is accepted as a valid float/double literal (NaN is rejected at construction, but infinity is a representable Iceberg double value). Converting such a literal to a DecimalType crashes with a bare decimal.InvalidOperation from inside Decimal.quantize, instead of the ValueError("Could not convert X into a Y") that every other impossible conversion in pyiceberg/expressions/literals.py raises:

• FloatLiteral.to(DecimalType)
• DoubleLiteral.to(DecimalType)

Describe how to reproduce the bug

from pyiceberg.expressions.literals import DoubleLiteral
from pyiceberg.types import DecimalType

DoubleLiteral(float("inf")).to(DecimalType(10, 2))
# decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>]
