Update file metadata

[jhoward1994]

What does it do?

Adds file metadata update capabilities to the existing FilesManager class:

1. New method in the FilesManager class:

   • update(id, data): Updates file metadata for a specific file by ID

2. Enhanced type definitions:

   • FileUpdateData interface for metadata update parameters
   • FileUpdateResponse type for the update operation result

3. Error handling for common update scenarios:

   • Non-existent file
   • Invalid update data format

Why is it needed?

The current implementation only allows retrieving files. This addition enables modifying file metadata in the Strapi Media Library.

How to test it?

1. Testing file metadata updates:

   // Update multiple attributes at once
   const updatedFile = await client.files.update(12, {
     name: "banner-image",
     alternativeText: "Company banner",
     caption: "For homepage header"
   });

2. Verify error handling:

   // Non-existent file handling
   try {
     await client.files.update(9999, { name: "test" });
   } catch (error) {
     console.error(error); // File not found error
   }

LGTM!

Just a nitpick, but could we replace all of these with something like:

  console.log(os.EOL);
  console.log('=== File Update Operations ===');
  console.log(os.EOL);

So that it's cleaner to read and works on windows?
