version.parse : exception during version parsing

[HarinadhD]

Below code snippet is working fine with the packaging version 21.3 , but throwing an error "Invalid version" on latest version (24.0 & 24.1)

test.py

import` os,sys,subprocess
from decimal import Decimal
from packaging import version
str1='8.9p1-8'
str2='8.9p1-6'
if version.parse(str1) > version.parse(str2):
    print("OK")

executing on version 24.0 & 24.1 :

#python3 test.py
Traceback (most recent call last):
  File "/root/test.py", line 9, in <module>
    if version.parse(str1) > version.parse(str2):
       ^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.11/site-packages/packaging/version.py", line 56, in parse
    return Version(version)
           ^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.11/site-packages/packaging/version.py", line 202, in __init__
    raise InvalidVersion(f"Invalid version: '{version}'")
packaging.version.InvalidVersion: Invalid version: '8.9p1-8'

executing on version 21.3:

#python3 test.py
OK

This behaviour is observed from version 22.0 and above , Is there any change in Version Specifiers Specifications ?

Please see #530 (which is also a pinned issue).
