I have made a python script and ran it on a clone of your git repo to confirm it works, simply run it at the root directory of wherever the files are, it will walk through and find module.json and do the replace.

#!/usr/bin/env python3

import re
import os

import fileinput

pattern = re.compile(r'(?P\.+)\"compatibility\":{\"minimum\":\"(?P\\d+)\",\"verified\":\"(?P\\d+)\"},(?P\.+)')

def make11(match):
    if match.groupdict().get('min', None) and match.groupdict().get('ver', None):
        return f"{match.groupdict()['pre']}\"compatibility\":{{\"minimum\":\"11\",\"verified\":\"11\"}},{match.groupdict()['post']}"

for root, dirs, files in os.walk("."):
    for file in files:
        if file == "module.json":
            for line in fileinput.input(f"{root}/{file}", inplace=True):
                print(re.sub(pattern, make11, line))

edit: lemmy is fucking with the formatting and removing the fucking regex group names, which will bork it. I've tried fixing it, dm me if you want me to send a downloadable link to the script
