[Bug]: Extra backslash when repairing JSON with escaped double quote

[didmar]

Version of the library

0.26.0

Describe the bug

It looks like repairing the object leads to escaped double quotes getting an extra backslash.

How to reproduce

Run the following snippet:

import json_repair

a = '{"foo": "\\"bar\\""}'
print(json_repair.loads(a))
# {'foo': '"bar"'}
# => OK!

b = """{
  "items": [
    {
      "foo": "\\"bar\\""
    }
"""
print(json_repair.loads(b))
# {'items': [{'foo': '\\"bar"'}]}
# => KO, expected {'items': [{'foo': '"bar"'}]}

c = """{
  "items": [
    {
      "foo": "\\"bar\\""
    }
  ]
}"""
print(json_repair.loads(c))
# {'items': [{'foo': '"bar"'}]}
# => OK!

Expected behavior

No extra backslash in the parsed string
