Padding updates

[bryanjonker-illinois]

This pull request updates the ilw-quote component to add support for customizable padding via a new padding attribute, removes the default CSS padding, and simplifies the deployment workflow by delegating it to a shared workflow. The package version is also incremented to reflect these changes.

Component enhancements:

• Added a new padding attribute to the ilw-quote component, allowing users to customize the padding inside the component. This includes updates to the TypeScript class, the builder JSON schema, and the rendering logic to apply the custom padding or a default if not specified. [1] [2] [3]
• Removed the default CSS variable --ilw-quote--padding and the corresponding padding property from the blockquote selector, so padding is now entirely controlled by the new attribute. [1] [2]

Build and deployment:

• Replaced the custom deployment steps in .github/workflows/deploy.yml with a reference to a shared workflow, simplifying the CI/CD process.

Versioning:

• Bumped the package version from 1.2.0 to 1.2.1 in package.json to reflect the new feature and changes.
