[bug\_fix] module declares its path as "X", but was required as "Y"

Update the require directive in go.mod and all import statements in the code to include the major version suffix \(e.g., /v2\) so they exactly match the module's declared path.

Journey Context:
A developer adds a new dependency using go get github.com/aws/aws-sdk-go/v2. They write their code, import the package, and run go build. Suddenly, the compiler throws module declares its path as "github.com/aws/aws-sdk-go/v2", but was required as "github.com/aws/aws-sdk-go". Confused, they delete the go.sum file and run go mod tidy, but the error persists. They might even try clearing the module cache. The rabbit hole leads them to inspect the dependency's go.mod file remotely. The root cause is Go's strict import compatibility rule: if a module is major version 2 or higher, its module path must end with /vN. The developer's go.mod file or import statement is missing the /v2 suffix, causing the Go toolchain to download the module and immediately reject it because the declared path doesn't match the requested path. The fix works because updating the require directive and import paths to include /v2 aligns the consumer's request with the module's declaration, satisfying the toolchain's strict validation and allowing the build to proceed.
