Fix TSApplicationGenerator to use Result<> instead of #{Result} (#4031)

The [earlier PR](#4010),
which ensured that a Smithy shape named `Result` does not conflict with
the Rust type `Result`, had a bug in `TSApplicationGenerator`. The
`rustTemplateBlock` was using `#{Result}` but `preludeScope` was not
passed in as a parameter.

This bug can be addressed in two ways:

1. Pass `*RuntimeType.preludeScope` to the `rustBlockTemplate` call
2. Remove `#{Result}` from `rustBlockTemplate` and continue using
`Result<>`

This PR implements the second approach because:

1. `TSApplicationGenerator` is slated for deprecation
2. The CI step `CI / PR Bot / Generate diff and upload to S3
(pull_request)` currently fails when comparing codegen between HEAD and
this version. Removing `#{Result}` is the most reliable way to avoid
parameter-passing issues with `rustBlockTemplate`
