ec2: deprecation warning when using `ec2.BastionHostLinux` with default values.

### Describe the bug

A warning will be generated if use the default values due to the use of a deprecated API in `ec2.BastionHostLinux`.

```
console.warn
[WARNING] aws-cdk-lib.aws_ec2.MachineImage#latestAmazonLinux is deprecated.
use MachineImage.latestAmazonLinux2 instead
This API will be removed in the next major release.

### Expected Behavior

No warnings should be displayed.

### Current Behavior

The following message is displayed:

```
aws-cdk-lib.aws_ec2.MachineImage#latestAmazonLinux is deprecated.
Use MachineImage.latestAmazonLinux2 instead
This API will be removed in the next major release.
```

### Reproduction Steps

```typescript
import * as cdk from "aws-cdk-lib";
import { Construct } from "constructs";

export class SandboxCdkStack extends cdk.Stack {
constructor(scope: Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);

const vpc = new cdk.aws_ec2.Vpc(this, "Vpc");

new cdk.aws_ec2.BastionHostLinux(this, "BastionHost", {
vpc: vpc,
});
}
}
```

### Possible Solution

Explicitly pass the `machineImage` argument.

Start in aws-ec2/lib/bastion-host.ts, focusing on the BastionHostLinux constructor path used when no machineImage is supplied. Reproduce the warning with the example in test/sandbox-cdk.test.ts, then verify the default path no longer emits the deprecation warning and the test still passes.
