chore: refactor Button API so that it can be used a standard button (#46880)

## Problem

Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.

## Solution

- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code

## How to test

As this is just prop renaming, if it builds it's ok
