fix(sam): allow "AWS::Lambda::Function" when validating #4282

Problem:
`validateTemplateConfig()` fails if the given resource is
"AWS::Lambda::Function", but:
1. its error message implies that "AWS::Lambda::Function" is allowed
2. 7b5aae7 implies that "AWS::Lambda::Function" is allowed
3. `getResourcesForHandlerFromTemplateDatum()` allows "AWS::Lambda::Function": https://github.com/aws/aws-toolkit-vscode/blob/8704f2cedb065087d7a85c9a9c40fc63d296f8cf/src/shared/fs/templateRegistry.ts#L184

ref #4281

Solution:
Update the condition to allow "AWS::Lambda::Function".
