Bug: bump_pydantic convert constr v1 regex to v2 pattern

[schlitzered]

Initial Checks

• I confirm that I'm using Pydantic V2

Description

bump_pydantic script should convert constr "regex" to "pattern"

i ran the bump_pydantic on my code base, and it did not convert anything, it seems it should at least convert constr(regex='') to constr(pattern='')

i am not sure if there is other stuff that bump_pydantic is missing,

Example Code

import pydantic

KUBE_SAVE_STR_30 = pydantic.constr(pattern="^(?![0-9]+$)(?!-)[a-z0-9-]{,30}(?<!-)$")

Python, Pydantic & OS Version

python 3.9
