feat: Adds personio_v2 provider (#3089)

<!-- Describe the problem and your solution --> 
The base url for the `Personio` provider was including the `v1` path so
I was not able to make calls to the the `v2` of the api. To not break it
for the current users I have followed the same approach that you have
used with the twitter api and decided to create the provider for the api
`v2` version.
