File Block: Enable User Customization of Download Button Appearance

[Mayank-Tripathi32]

What problem does this address?

1. Current file block uses RichText for the download button which limits styling/functionality
2. Difficult to customize button appearance and behavior
3. Inconsistent with WordPress's block system for button handling

What is your proposed solution?

Replace the current RichText-based download button with an InnerBlocks implementation that specifically allows the core Button block. This solution leverages WordPress's existing button block infrastructure while maintaining the essential download functionality. The InnerBlocks approach provides several key benefits:

The solution maintains download functionality while providing access to familiar button controls, creating a better experience for both users and developers.
Key benefits include full theme.json support, consistent editing experience, and simplified maintenance, all while preserving essential download capabilities through proper template locking.

By enforcing a template lock and specific configuration, we ensure the download functionality remains intact while opening up enhanced styling and customization capabilities. This creates a better balance between maintaining core functionality and providing improved user control over the button's appearance.

related issue #57871 that recommends using file component for download links, but I need some inputs on "download" attribute if we go ahead with innerblock implementation

This is a duplicate of #57314. I would recommend searching for existing issues before creating a new one. Helps to avoid duplicates, and usually, old issues have more context.

Thank you for pointing that out. I did search for existing issues but might have missed this one. My apologies!

No worries, @Mayank-Tripathi32!

My trick is to narrow it down using labels. Each block has a separate label, so when I want to report something, let's say an Image block related, I'll filter issues first by label and then search keywords.
