Escaping double quote doesn't work when it is followed by slash('/') character

When input string has double quote character followed by slash('/') character which is part of string value, it throws error.
Double quote without slash works fine.

Below code fails
```
const text = '{"name":"Parth","value":"This is test "message/stream"';
const parsed = jsonrepair(text);
```
with below error
```
FAIL src/index.test.ts > jsonrepair ['regular'] > repair invalid JSON > should handle missing escaping of double quotes followed by a slash
Error: Object key expected at position 39
❯ throwObjectKeyExpected src/regular/jsonrepair.ts:891:11

890| function throwObjectKeyExpected() {
891| throw new JSONRepairError('Object key expected', i)
| ^
892| }

❯ flush src/streaming/core.ts:96:12
❯ jsonrepair src/index.test.ts:774:5
❯ src/index.test.ts:695:22
```

If I remove slash after double quote it works. So below example works
```
test("should handle missing escaping of double quotes followed by a slash", () => {
const text = '{"name":"Parth","value":"This is test "message/stream"';
const parsed = jsonrepair(text);

expect(parsed).toBe(
'{"name":"Parth","value":"This is test \\"message/stream"}'
);
});
```

Start with the failing test in src/index.test.ts, then trace the reported positions in src/regular/jsonrepair.ts and src/streaming/core.ts. Check both repair paths for a missing escape before a double quote followed by a slash. Done means the test passes for regular and streaming modes and produces the expected repaired string.
