When running e2e tests on flaky networks, gravatar can cause a timeout
and test failures. Turn off, and populate avatars on e2e test suite run
to make them reliable.

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.
