[Example] Add APIGatewayV1 example

[everyplace]

This PR adds an APIGateway V1 example, which differs slightly from the existing V2 example.

Motivation:

While APIGatewayV2 has existed for a while, there are still some scenarios where V1 is preferable (see Choose between REST APIs and HTTP APIs for more details). This PR adds a working example for the Api endpoint type.

Modifications:

Sources/main.swift

• Swapped APIGatewayRequestV2 and APIGatewayResponseV2 for their unversioned counterparts (aka V1).

template.yaml

• Changed the Events name and corresponding Type: Api values.
• Added necessary additional properties to define a GET endpoint for an Api endpoint.

Readme.md

• Updated the request and response example outputs.

Result:

Now, an APIGateway and APIGatewayV1 example exist.

Note

It is the author's opinion that this new example should technically be called APIGateway and the existing one should be renamed to APIGatewayV2 to keep consistent with the request and response type naming conventions, but this is omitted from this request to be less disruptive.

Thank you for this PR.
Congrats for submitting a PR that passes all the tests at first attempt :-)

I suggested two minor changes in the review.

Can you also add this test to the CI (this line)?

I like your suggestion to rename to existing APIGateway example to ...V2. Let's keep this one as ...V1, so, at the end, we will have Examples/APIGatewayV1 and Examples/APIGatewayV2 and Examples/APIGatewayV2+LambdaAuthorizer

If you have time, can you submit a PR for this change too (don't forget to change the CI too :-) )

LGTM, just two tiny changes

I would update this to 2025

I know it's coming from the example you copied, but I would use 128Mb here. This is enough to run the function and it reduces costs for customers.
I will add a GH issue to remember doing the same on all SAM examples.
