fix: various typos (#813)

To upgrade to the new release, update `tag` to `v0.0.14-alpha`:

```

[dependencies]

# eg. S3:

# e.g. S3:

aws-sdk-s3 = { git = "https://github.com/awslabs/aws-sdk-rust", tag = "v0.0.14-alpha" }

```

- :tada: Add support for EKS (smithy-rs#553)

- :warning: **Breaking Change:** httpLabel no longer causes fields to be non-optional. You may need to adapt code that uses models. (#537)

- :warning: **Breaking Change:** `Exception` is **not** renamed to `Error`. Code may need to be updated to replace `Error` with `Exception` when naming error shapes.

- :warning: **Breaking Change:** Models are now in strict pascal case including acronyms (eg. `dynamodb::model::{SSESpecification => SseSpecification}`)

- :warning: **Breaking Change:** Models are now in strict pascal case including acronyms (e.g. `dynamodb::model::{SSESpecification => SseSpecification}`)

- Add more SES examples, and improve examples for Batch.

- Improved error handling ergonomics: Errors now provide `is_<variantname>()` methods to simplify error handling

- :bug: Bugfix: Fix bug in `create_multipart_upload`: #127 (smithy-rs#531, @eagletmt)

- Types represented by the Smithy `Set` type now generate `Vec<T>` in all cases. This is also technically breaking but not currently exposed. (smithy-rs#270)

- Bugfix: The `.message()`field of errors will now look for both `message` and `Message` in the model (smithy-rs#374)

- Add support for the `AWS_REGION` environment variable. (smithy-rs#362)

- The request type generated by the fluent builders, eg. `dynamodb.list_tables()` is now `Debug` (smithy-rs#377, @declanvk)
