Issue:
fromHttp fails for Wednesdays
**Describe the bug**
A clear and concise description of what the bug is.

**To Reproduce**
Please share a minimal code example that triggers the problem:
```js
it("Monday", () => {
  const str = "Monday, 27-Jun-22 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});
it("Tuesday", () => {
  const str = "Tuesday, 28-Jun-22 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});
it("Wednesday", () => {
  // FAILS
  const str = "Wednesday, 29-Jun-22 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});
it("29-Jun-21", () => {
  const str = "Tuesday, 29-Jun-21 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});
it("Thursday", () => {
  const str = "Thursday, 30-Jun-22 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});
it("Friday", () => {
  const str = "Friday, 01-Jul-22 08:49:37 GMT";
  expect(DateTime.fromHTTP(str).isValid).toBe(true);
});

/*
   √ works
   √ Monday
   √ Tuesday
   × Wednesday
   √ Wednesday 2021
   √ Thursday
   √ Friday
*/

```

**Actual vs Expected behavior**
I expect fromHTTP to work for 29 Jun 2022, instead I'm getting parse error.

**Desktop (please complete the following information):**

- OS: Windows 11
- Browser Node 18.4.0
- Luxon version 2.4.0
- Your timezone Sydney (AEST)

**Additional context**
Add any other context about the problem here.
`"Wed, 29 Jun 2022 08:05:35 GMT"` works but not `Wednesday, 29-Jun-22 08:49:37 GMT`
