feat: add support to resize attachments

[drodil]

Need to think if this is needed feature..

It'd be quite heavy process adding it to backstage directly, maybe something like https://www.npmjs.com/package/imagemin as a third party service, and have a config setting to pass the image to it to then return a compressed version?

@veenarm yeah, not sure it's a necessary feature as there's already size limiting. Probably will not merge this ever. What would instead be useful is that users could select the part of the image to be shown in different sizes. Now it can scale the image a bit weird way in some screen sizes or use cases.
