Xavier Vello 147ae2c5be Fix opengraph meta for wiki pages (#4427)
Fixes https://codeberg.org/forgejo/forgejo/issues/4417 by adding a conditional branch to the `head_opengraph` template to match wiki pages. I tried to be consistent with the other types:

- `og:title` is the wiki page title
- `og:url` is built via `{{AppUrl}}{{.Link}}` like it is done for commit and file views. This has the caveat of doubling the slash (see test below). Should we `{{trimSuffix "/" AppUrl}}` to remove this, if sprig is available?
- `og:description` is the repository description to match GH behaviour. Also, the first sentences of the page might not be descriptive enough. Should we prefix the repo description with the repo name?
- `og:type` and `og:image` are common

Added a `TestOpenGraphProperties` integration test using existing fixtures. Coverage is not 100% but can be improved later.

## Output on a test repo

```html
<meta property="og:title" content="Project architecture">
<meta property="og:url" content="http://localhost:3000//xvello/wiki-test/wiki/Project-architecture">
<meta property="og:description" content="description for a test project">
<meta property="og:type" content="object">
<meta property="og:image" content="http://localhost:3000/avatars/3dd4d1e4eef065d1b4ad4bdb081ab6e7">
```
