modules/lsp: add inotify-tools package when any lsp server is enabled

Before this change `:LspInfo` complains about `vim.lsp` using `libuv-watchdirs` for file watcher:

```
vim.lsp: File Watcher ~
- File watch backend: libuv-watchdirs
- ⚠️ WARNING libuv-watchdirs has known performance issues. Consider installing inotify-tools.
```

This commit adds `inotify-tools` as extra package when any of the lsp servers is enabled via `lsp.servers.*.enable` option, so the warning goes away.
