Upgrading from 1.12.10 to 1.12.17 is a breaking change.

Expected Behavior

You expect when bumping the micro version from 10 to 17 that nothing breaks.

Actual Behavior

You previously merged APIs with Api1.combine(Api2).combine(Api3) however this has been removed in 1.12.17 it seems opting for the (more readable) (Api1, Api2, Api3) approach.

Steps to Reproduce the Problem

1. Create an example API with poem 1.12.10 merging two Api's using the combine() method.
2. Bump the micro version to 1.12.17
3. Observe new compile errors.

Just as a note i'm aware that this was changed/removed in 1.12.11 however cargo will auto bump the version because it's 1.x and it's a micro version which was a bit un-expected.

IDE can't recognize the combine method makes me unbearable. 😁
