chore(deps): bump @slack/bolt from 5.0.0 to 5.1.0 in /examples/custom-receiver

[dependabot]

Bumps @slack/bolt from 5.0.0 to 5.1.0.

Changelog

Sourced from @​slack/bolt's changelog.

5.1.0

Minor Changes

• 6cf7b0c: Enforce a configurable request body size limit in HTTPReceiver and ExpressReceiver to prevent unauthenticated large-body denial-of-service attempts. Both receivers previously buffered the entire request body into memory before signature verification, so a flood of large invalid requests could exhaust memory and crash a publicly exposed app.

  Both receivers now reject request bodies larger than a new bodyLimit option with an HTTP 413 response before the whole body is buffered. The limit is enforced on the bytes actually received (not the Content-Length header, which a client controls) and applies even when signatureVerification is false. It defaults to 4194304 (4 MB); pass a different number of bytes, a bytes-style string like '4mb', or Infinity to disable it (not recommended in production).

  This is a security fix with a minor behavioral change: requests with bodies larger than 4 MB are now rejected with 413 by default (previously unbounded). Apps that legitimately receive larger payloads can raise bodyLimit on the receiver.

Patch Changes

• b9acd4f: Fix AwsEventV1.multiValueQueryStringParameters to allow null, matching the actual AWS API Gateway payload and the @types/aws-lambda APIGatewayProxyEvent type. This resolves the type error when passing an APIGatewayProxyEvent directly to the handler returned by AwsLambdaReceiver.
