--- BEGIN ISSUE ---
[Bug]: abfallwirtschaft_pforzheim_de has change the URL.
### I Have A Problem With:

A specific source

### What's Your Problem

The URL changes from "https://www.abfallwirtschaft-pforzheim.de/kundenportal/abfallkalender" to "https://www.abfallwirtschaft-pforzheim.de/abfallkalender". On the new Site you need to select a checkbox for the year. I think this option would disappear on the beginning of the next year. But the addon doesnt show me the calendar for 2023 anymore. Its complete empty.

### Source (if relevant)

abfallwirtschaft_pforzheim_de

### Logs

```Shell
no relevant logs
```


### Relevant Configuration

```YAML
abfallwirtschaft_pforzheim_de
```


### Checklist Source Error

- [ ] Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
- [ ] Checked that the website of your service provider is still working
- [ ] Tested my attributes on the service provider website (if possible)
- [X] I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

### Checklist Sensor Error

- [ ] Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)

### Required

- [X] I have searched past (closed AND opened) issues to see if this bug has already been reported, and it hasn't been.
- [X] I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.
