Python requests banned?

**Describe the bug**
I am building a Python app and part of it interfaces with the Adoptium API. Using the Requests library, which sends user-agent `python-requests/2.31.0` by default, gives a 403 forbidden error. Not sending a user-agent at all also causes a 403 forbidden. Setting the user-agent to something else fixes the issue, but it shouldn't be a necessary workaround, any user-agent should be allowed.

**To Reproduce**
1. `pip install requests`
2. Write a file like this:

```py
import requests
resp = requests.get("https://api.adoptium.net/v3/info/available_releases")
print(resp.request.headers)
print(resp.headers)
print(resp.status_code)
print(resp.text)
```

4. Run it. Observe 403 error (e.g. first screenshot)
5. Change second line of file to be like this:

```py
resp = requests.get("https://api.adoptium.net/v3/info/available_releases", headers={"User-Agent": "Dummy"})
```

6. Run it again. Observe it works. Wow!

**Expected behavior**
It works with the default requests config

**Screenshots**
Doesn't work with the regular header.

Works when you put some random one. Crazy stuff, one http header is the entire difference between failure and success.

**Device (please complete the following information):**
- OS: macOS Ventura 13.3.1
- Browser: N/A
- Version: N/A

**Additional context**
Looks to be an azure misconfiguration. Also this [happened before](https://github.com/adoptium/api.adoptium.net/issues/575) but it wasn't fixed properly.

Start by reproducing the request in the issue with the default Python Requests user-agent, then inspect the API's Azure configuration and compare the earlier issue #575. Done means the available-releases endpoint returns successfully without requiring a custom User-Agent header.
