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">
```

In #26851, it assumed that `Commit` always exists when
`PageIsDiff==true`.
But for a 404 page, the `Commit` doesn't exist, so the following code
would cause panic because nil value can't be passed as string parameter
to `IsMultilineCommitMessage(string)` (or the StringUtils.Cut in later
PRs)
1. The `og:description` should be "a one to two sentence description of
your object"
* It shouldn't output all the user inputted content -- it would be
pretty huge.
* Maybe it only needs at most 300 bytes.
2. Do not render commit message as HTML
Add more useful Open Graph metadata for commit and file URLs:
- Set `og:title` to the page title, which is a concise summary in both
cases (`<commit message> ยท <commit hash>` and `<filename> at <branch>`,
respectively)
- Set `og:description` to the commit message body, if available
- Set `og:url` to the relevant URLs instead of the repo URL
Also move the relevant meta tags into a separate template as they now
take up the majority of the base head template.
