feat!: Remove function literal with receiver.

[arriolac]

Since the change introduced in #43, certain await* extensions do no require function literal with receivers anymore. This PR removes those arguments from those calls as no further configurations can be made to the underlying builder objects.

1. Will this automatically update the documentation?
2. I don't see anything in the demo app that needs to be updated, perhaps becase none of the affected await* functions are demonstrated. Please confirm.

1. Will this automatically update the documentation?

Yep. Once this pull request is merged the docs.yml workflow will be kicked off which should create a pull request to update the documentation for places-ktx. There are more automations in place which will automerge the pull request once checks have passed.

2. I don't see anything in the demo app that needs to be updated, perhaps becase none of the affected await* functions are demonstrated. Please confirm.

Yep! That's correct that the demo app doesn't need to be updated since none of the affected await functions are being used. Perhaps we should update the demo app though to demonstrate one of these functions. I'll file a separate issue for this (edit: I created #105).
