[Bug]: Angular signal inputs that are aliased don't work properly

Describe the bug

Angular allows to alias inputs, for example when kebab-case attribute names are desired (see here). When I do so and assign such attribute a value in the args list then it seems the signal isn't getting the correct value (InputSignal<string>) but the value itself directly.

Related to #25784 and PR #26413

Reproduction steps

1. Go to above link
2. Navigate to the story Example\Button\Works
3. Open Devtools' console which will not show errors about backgroundColor (which is aliased)
4. Navigate to the story Example\Button\Broken
5. In Devtools' console there will be error messages about backgroundColor only. The attribute foregroundColor is not mentioned and the only difference is it not being aliased in the component.

ERROR TypeError: ctx.backgroundColor is not a function
    at ButtonComponent_Template (template.html:6:3)

The broken story defines both attribute in the args, that seems to "activate" the difference.
