Simplify Basic Inputs into a Single Input

As a website maintainer,
I want better maintainability of basic input components,
So that it is easier to understand the code base's structure/workflow.

Context

In Scope

• Combine the relevant basic inputs into a single input component.
• Update the references to these basic inputs to ensure that there are no errors.
• Placeholder prop should be optional as it's needed for some inputs (like text), but unused for most

Out of Scope

• Combining custom inputs into a single input component.
• The select (used for gender) is out of scope as it is not an HTML input element.
