Re-annotate models

Make `code` elements in links display as such

When a link consisted only of an inline code block -- ```[`like this`](https://google.com/)``` -- it was hard to tell that it was even a link.

Fix multi-line syntax highlighting

### What does this MR do?

This MR fixes multi-line syntax highlighting in the code views. HTML span elements only apply to a single line, and in the case of multi-line comments, the highlighting was dropped as a result. Ensure that each line has
the proper styling to fix this.

### Why was this MR needed?

The current styling was broken for a while.

### Screenshots

Check that hooks directory exists before attempting to call realpath

This MR checks that the hooks directories actually exist before attempting to resolve their `realpath`.

Users who attempted to restore from source to an omnibus installation would get ugly errors when running `gitlab-rake gitlab:check`:
