Subject: [PATCH] Use correct README link to render the README (#23152)
 (#23264)

Backport #23152

`renderReadmeFile` needs `readmeTreelink` as parameter but gets
`treeLink`.
The values of them look like as following:
`treeLink`:  `/{OwnerName}/{RepoName}/src/branch/{BranchName}`
`readmeTreelink`:
`/{OwnerName}/{RepoName}/src/branch/{BranchName}/{ReadmeFileName}`

`path.Dir` in

https://github.com/go-gitea/gitea/blob/8540fc45b11eff9a73753ca139f8ea5c38509bf5/routers/web/repo/view.go#L316
should convert `readmeTreelink` into
`/{OwnerName}/{RepoName}/src/branch/{BranchName}` instead of the current
`/{OwnerName}/{RepoName}/src/branch`.

Fixes #23151
