lsp: Handle unregistration "textDocument/rename" from a server (#19427)

Hi. While working on https://github.com/zed-industries/zed/pull/19230 I
noticed that some servers send a request to unregistered the
`textDocument/rename` capability. I thought it would be good to handle
that message in Zed:

```plaintext
[2024-10-18T21:25:07+02:00 WARN  project::lsp_store] unhandled capability unregistration: Unregistration { id: "biome_rename", method: "textDocument/rename" }
```

So this pull request implements that. Thanks.
