v0.17.11 - AWS bugfix, client methoddeprecation, internal refactors

This is mostly a bugfix and cleanup release.

What's Changed

• [aws] Keep casing in file credential provider by @kubukoz in #1076

Resolves a case-sensitivity issue in the file-based AWS credentials provider.

• Deprecate ClientBuilder.use, add .make by @kubukoz in #1073

Deprecates a method - the migration path would be just to move to another one with the same shape.

• Error transformations as middleware by @msosnicki in #1084

Changes the error transformation logic in the http4s servers so that it's implemented using the (public) per-endpoint middleware construct.
