feat(storage-s3): add cacheControlMaxAge option

This PR introduces a new configuration option for the S3 storage plugin, allowing users to specify a cacheControlMaxAge value in seconds.

The default value is undefined which omits the Cache-Header keeping this change non-breaking.

No Cache-Control header present on uploads beging returned.

After changes

If cacheControlMaxAge is set, Cache-Control: public, max-age={cacheControlMaxAge} is added to uploads returned.

Using plugin

s3Storage({
      ...
      cacheControlMaxAge: 31536000,
    }),

• I have read and understand the
  CONTRIBUTING.md
  document in this repository.

Type of change

• New feature (non-breaking change which adds functionality)

Checklist:

• Existing test suite passes locally with my changes
• I have made corresponding changes to the documentation

I wonder if we can replace cacheControlMaxAge with something like responseHeaders that also can be a function.

[1b0t]

Great idea. I think it should be possible.

I tried to keep it consistent with the Vercel blob adapter for this PR.
