[PW-3240] /adjustAuthorisation is not implemented

[slallema]

Is your feature request related to a problem? Please describe.
I need to modify the amount of some credit card authorisations I make

Describe the solution you'd like
I would like the API call https://docs.adyen.com/api-explorer/#/Payment/v52/post/adjustAuthorisation to be supported by the python client

Describe alternatives you've considered
For now I create several authorisations when needed but this is suboptimal
