Fix batch query issue when primary key is -1

See merge request gitlab-org/gitlab!51716

AuditEvents loaded via BatchLoader were
behaving strangely and displaying incorrect
author information when the collection
includes rows with no author. Because
records without an author are stored as -1,
this created unexpected behaviour.

Render WebP attachments as image by default

See merge request gitlab-org/gitlab!51088

This adds the .webp file extension to the list of safe image extensions
in the file type detection. It allows webp-images to be uploaded to
issues and comments which then get embeded as images instead of
attachments (see [gitlab-org/gitlab#296600](3)). It also allows uploading
of designs in the webp format. WebP is supported in all browsers that
GitLab supports except Safari <= macOS 10
(see [caniuse][1], [suppported browsers][2]).

Allow user SSH public key endpoint to be publicly accessible again

See merge request gitlab-org/gitlab!52227

A regression caused the User SSH public key endpoint to require
authentication when instance public visibility was restricted.
This endpoint should be available without authentication, matching
the behavior of the /api/v4/users/:id/keys endpoint.
