fix: use unique name to avoid issues when running in the CI

[v1v]

tear-down does not cleanup the aws_cloudwatch_log_group, I'd assume is because the retention policy is honoured.

Therefore, it's required to use an unique name, otherwise it will fail with:

Error: creating CloudWatch Logs Log Group (/aws/lambda/github-actions-smoke-testing-test): operation error CloudWatch Logs: CreateLogGroup, https response error StatusCode: 400, RequestID: 4161b73e-8b5b-4fef-8a17-64aa29c2cdd4, ResourceAlreadyExistsException: The specified log group already exists

  with aws_iam_policy.lambda_logging,

It creates a new resource:

I think I need something else... I'm testing it out

The IAM policies were also causing issues; I've just created a test branch to test these changes in isolation and avoid spamming. I'm gonna run a few more workflows to validate things works as expected.

So far:

• https://github.com/elastic/apm-aws-lambda/actions/runs/10284636972 worked fine.

-> Calling the lambda function...
{
    "StatusCode": 200,
    "ExecutedVersion": "$LATEST"
}
{
    "StatusCode": 200,
    "ExecutedVersion": "$LATEST"
}
-> Waiting for the agent documents to be indexed in Elasticsearch...
-> Smoke tests passed!

• https://github.com/elastic/apm-aws-lambda/actions/runs/10285279991 is another run, if no leftovers then it should be green, if so I'll update this PR with the remaining changes
