feat(rds): implement setting parameter group name

[LaurenceWarne]

Reason for this change

I'd like to be able to set RDS parameter group names using CDK.

Description of changes

I've added a new field name to ParameterGroupProps used to populate dbClusterParameterGroupName and dbParameterGroupName where appropriate - AFAICS this couldn't be done at this level previously?

Description of how you validated changes

I've altered a couple of unit tests and an integration test. However I'm unable to run the integration test as the postgres version in the existing snapshot is deprecated (I believe this needs to be deployed before the new snapshot?) which blocks me from deploying.

Hi @LaurenceWarne, thank you for the contribution!

Regarding your clarification request, you could update the README here by adding the new name property to the sample code. It's a fairly simple change so that should be sufficient.

With regards to the integ test, I've pulled your code down and tested it an ran into the same issue. I was able to resolve it by doing 2 things:

1. Delete the existing snapshot folder for that integ test
2. Change the rds.PostgresEngineVersion to a supported version: ``rds.PostgresEngineVersion/VER_16_2and rerun the test with the--update-on-failed` flag to regenerate the new snapshots.

Thanks for the guidance, should be done in the most recent commit!

If you like I can raise an issue for the other integration tests that use the same deprecated version.

✅ Updated pull request passes all PRLinter validations. Dismissing previous PRLinter review.

Suggested change

	* @default CloudFormation-generated name
	* @default - CloudFormation-generated name

Something I learned recently, if the value immediately after a @default tag is not the actual value but rather a sentence describing the value, you need to separate it with a dash - or else it would think that Cloudformation-generated is the default value.

This looks good, nice work @LaurenceWarne!

And no worries, I can create an issue to update the existing integ tests using the deprecated postgres versions. Thanks again!
