aws-ec2: ec2.AmazonLinux2Kernel is not an enum in Python

### Describe the bug

In Python, AmazonLinux2Kernel is not an enumeration (not an enum.Enum) in CDK -

```python
ec2.AmazonLinux2Kernel.KERNEL_5_10 == ec2.AmazonLinux2Kernel.KERNEL_5_10
False
```

vs

```python
ec2.AmazonLinuxGeneration.AMAZON_LINUX_2023 == ec2.AmazonLinuxGeneration.AMAZON_LINUX_2023
True
```

We can see that the class of this is not an enumeration, like other enumerations in the aws-ec2 code:

```python
class AmazonLinux2Kernel(
metaclass=jsii.JSIIMeta,
jsii_type="aws-cdk-lib.aws_ec2.AmazonLinux2Kernel",
):
'''Amazon Linux 2 kernel versions.

:exampleMetadata: infused
# ...
# vs

@jsii.enum(jsii_type="aws-cdk-lib.aws_ec2.AmazonLinuxGeneration")
class AmazonLinuxGeneration(enum.Enum):
'''What generation of Amazon Linux to use.
# ...
```

This inconsistency means it is difficult to compare certain objects in python.

### Expected Behavior

I expected an enumeration to be an enumeration - the comparison above should have passed.

### Current Behavior

The enumeration was not an enumeration, and the comparison above failed.

### Reproduction Steps

The code above should suffice.

### Possible Solution

Make these enumerations, enumerations.

Start by locating the AmazonLinux2Kernel and AmazonLinuxGeneration definitions in aws-ec2 and comparing how their Python types are generated through jsii. Reproduce the equality check from the issue and trace the generated Python class; done means AmazonLinux2Kernel behaves as an enum and the comparison passes without regressing the existing AmazonLinuxGeneration behavior.
