Describe the bug / provide steps to reproduce it

Even if a language server supports rename, if it doesn't support prepareRename it seems to silently fail the rename action from the user.

1. Use a language server implementation that doesn't support prepareRename, luau-lsp for my example
2. Try to rename a symbol with either F2 or editor: rename
3. Notice nothing happens and nothing is logged to the lsp logs or zed logs

Expected result:
I expect it to allow me to rename the symbol like VSCode, Neovim, and numerous other text editors even if the server does not support prepareRename.

This may also be an issue if the language server doesn't support documentHighlight but I haven't done enough research to conclude this.
