chore: upgrade the aws dependencies in deltalake-aws

[rtyler]

With the recent MSRV change for the newest datafusion release, finally
time to upgrade some of these.

In the course of doing this, I decided to get rid of the unnecessary
maplit crate dependency here. Making HashMaps isn't that hard 😄
