#### Describe the bug
As part of the upgrade of `follow-redirects` in https://github.com/axios/axios/pull/2689, a default `maxBodyLength` of 10MB began to be enforced (previously, there was no request payload limit). There are a few issues with this:
1. The default limit is not mentioned in the `axios` documentation
2. This change in defaults is not included as a breaking change in the `axios` changelog
3. The default is unlimited when `maxRedirects = 0`

#### To Reproduce
```js
axios.post('/size', 'x'.repeat(1e8))
// -> Error: Request body larger than maxBodyLength limit

axios.post('/size', 'x'.repeat(1e8), { maxBodyLength: -1 })
// -> Error: Request body larger than maxBodyLength limit

axios.post('/size', 'x'.repeat(1e8), { maxRedirects: 0 })
// -> OK

axios.post('/size', 'x'.repeat(1e8), { maxBodyLength: Infinity })
// -> OK
```

#### Expected behavior
The default `maxBodyLength` should be consistent and documented, regardless of the value of `maxRedirects`.

#### Environment
 - Axios Version: 0.24.0
 - Adapter: HTTP
 - Browser: N/A
 - Browser Version: N/A
 - Node.js Version: 16.13.0
 - OS: OS X 11.6
 - Additional Library Versions: N/A

#### Additional context/Screenshots
This is related to https://github.com/axios/axios/pull/3786, although I don't think that PR goes far enough to correct the inconsistent behavior.
