Environment

SaaS (https://sentry.io/)

Steps to Reproduce

Attach a JSON file and try to view it within the issue page. The preview option is greyed out with the text: Attachment cannot be previewed

A user got around this by adding contentType.
It's a property on the attachment object
const filename = 'XXX.json';
const contentType = 'application/json'; // helps show Preview in Sentry
hint.attachments = hint.attachments || [];
hint.attachments.push({ filename, data, contentType });

We should try to derive the content type from the file name.

Expected Result

Can view the payload in the issue.
