chore: update to ameba 1.7.0 and adapt most of the code to it (#6082)

* chore: update to ameba 1.7.0 and adapt most of the code to it

* forgot to add this to build ameba into the ./bin directory for use, as ameba does not longer offer a postinstall script

* forgot to update ameba in the shards files

* remove leftover : in rescue

* Use ameba linter action instead of installing it with shards
